This paper estimates the permanent and transitory movements in U.S. output and the unemployment rate and the relationships between them. The results suggest that permanent movements in U.S. output and the unemployment rate are important for explaining overall fluctuations. Further, the correlation between changes in these series arises in large part due to the relationship between their permanent components. [ABSTRACT FROM AUTHOR]

The United States spends nearly 1/5th of its GDP on healthcare. Yet, to achieve value‐based care, the Economist describes the US healthcare system as handicapped by multiple, disparate silos that prevent the organization and sharing of data. This paper explores the current state of clinical oncology drug research and its relationship to value‐based cancer care. Clinical Chemotherapy Pathways are proposed as a unifying structure to bring together disparate sources of data to increase value. [ABSTRACT FROM AUTHOR]

We examine the relationship between offshoring and the labor market in an occupational choice model of trade and endogenous growth where workers are employed on the basis of their individual skill levels. Trade liberalization leads to offshoring and reduces employment in the manufacturing sector. Displaced workers move into traditional and innovation sectors according to their skill levels, shaping real wages and aggregate productivity in the manufacturing sector. The paper aims to show how inter-sectoral labor market adjustments, highlighted by skill heterogeneity, could be a possible explanation for the simultaneous rise in productivity and reduction in real wages that have coincided with the sharp escalation of offshoring activities in the U.S. manufacturing sector since 2004.

This paper uses an autocorrelation function (ACF) approach to develop a new testing procedure for international output convergence. We define convergence in terms of sample ACFs of detrended output per capita, and construct an inference set-up based on resampling and subsampling techniques for dependent data. Using per capita GDP for 15 OECD countries observed over a century, we find that the hypothesis of conditional convergence is unsupported; that, the USA apart, the linearized neoclassical growth model fails to replicate the transitional dynamics of OECD economies; and that these economies do not behave like a club.

This article develops a growth-based regionalisation of the United States using both principal components and cluster analyses to endogenously sort states into regional transition clubs with somewhat uniform annual rates of per capita real GSP growth in the period 1977–2004. I correlate the principal components with annual growth in per capita real GDP and assess spatial dependencies in the identified transition clubs. Growth variability in the transition clubs is compared with growth variability in BEA and Census regions. Results show a large Coastal transition club that contains most of the New England, Middle Atlantic, and South Atlantic census regions. California, Minnesota, and Arizona belong to this grouping. A second growth transition club titled Eastern Interior groups most of the states in the East North Central and the East South Central census regions. A Western Interior region groups states in the southern Great Plains. Coefficients of variation show that these three large interstate groupings grow more uniformly compared with associated census and BEA regions. Growth in western states is idiosyncratic. Most western states group with one or two related states, California and Arizona associate with the Coastal club, Nevada does not pigeonhole well with other states, and Alaska's annual growth trajectory is unique. Este artículo desarrolla una regionalización de los Estados Unidos basada en crecimiento usando componentes principales y análisis de cluster para agrupar los estados en grupos de transición regional según tasas anuales de crecimiento más o menos uniformes en el producto estatal bruto (GSP) real per capita en el periodo 1977–2004. Correlaciono los componentes principales con el crecimiento anual en el producto interior bruto (GDP) real per capita y evalúo dependencias espaciales en los grupos de transición identificados. La variabilidad de crecimiento en los grupos de transición se compara con la variabilidad de crecimiento en regiones BEA (Bureau of Economic Analysis) y Censuales. Los resultados muestran un grupo de transición grande en la Costa que contiene la mayoría de regiones censuales de New England, Atlántico Medio, y Atlántico Sur. California, Minnesota, y Arizona pertenecen a este grupo. Un Segundo grupo de transición de crecimiento llamado Interior Este aglutina la mayoría de estados de las regiones censuales Central Norte Oriental y Central Sur Oriental. Una región Interior Occidental agrupa los estados de las Grandes Llanuras del Sur. Los coeficientes de variación muestran que estos tres grandes grupos interestatales crecen más uniformemente en comparación con las regiones censuales y BEA asociadas. El crecimiento en los estados occidentales es idiosincrásico. La mayoría de los estados occidentales se agrupan con uno o dos estados relacionados, California y Arizona se asocian con el grupo de la Costa, Nevada no se clasifica bien con ningún otro estado, y la trayectoria de crecimiento anual de Alaska es única.

This paper outlines a class of statistical procedures that permit testing of a broad range of multidimensional stochastic dominance hypotheses and, more generally, welfare hypotheses that rely upon multiple stochastic dominance conditions. We apply the procedures to data on income and leisure hours for individuals in Germany, the UK, and the USA. We find that no country first-order stochastically dominates the others in both dimensions for all years of comparison. Furthermore, while in general the USA stochastically dominates Germany and the UK with respect to income, in most periods Germany stochastically dominates with respect to leisure hours. Finally, we find evidence that bivariate poverty (which refers, for example, to the working poor, that is, those who have little leisure and low income) is lower in Germany than in either the UK or the USA. On the other hand, poverty comparisons between the UK and the USA are sensitive to the subpopulation of individuals considered. Copyright © 2007 John Wiley & Sons, Ltd. [ABSTRACT FROM AUTHOR]

The share of gross domestic product from the service industry reflects the competitiveness of a nation; the service industry in the USA accounts for around 80% of its gross domestic product, and it has been increasing gradually. Continual innovations and advances in enabling technologies for the service industry are crucial for developed countries to sustain their leading positions in the globalized economy. To clarify future research directions of operations research (OR) in the service industry, the state of art of OR has been examined systematically, the new requirements of OR are identified for its applications in service industries in comparison with those in manufacturing industries, and the limitations of existing methodologies and tools have been discussed. This paper was intended to provide an updated review on how OR has been applied in the service sector in recent years and what directions the study of OR will be carried forward in the near future. Under a proposed research framework, recent OR-related articles were collected from 17 leading OR journals and classified into the five most active sectors, that is, transportation and warehousing, information and communication, human health and social assistance, retails and wholesales, and financial and insurance services. The conclusions on the limitations of existing studies and the demanding ORs in the service have been drawn from our summaries and observations from a comprehensive review in this field.

What was hiding behind the aggregate commercial bank loans through the end of 2008? We use balance sheet data for every insured U.S. commercial bank from 1999:Q1 to 2008:Q4 to construct credit expansion and credit contraction series and provide new evidence on changes in lending. Until 2008:Q3 net credit growth was not dissimilar to the 1980 and 2001 recessions. However, between the third and fourth quarter credit contraction grew larger than credit expansion across all types of loans and for the largest banks. With the inclusion of 2008:Q4 data our series most resemble the intensification of the Savings and Loan crisis. [ABSTRACT FROM AUTHOR]

The aim of this paper is to identify the different sources of persistence of output fluctuations. We propose an unobserved components model that allows us to decompose GDP series into a trend component and a cyclical component. We let the drift of the trend component switch between different regimes according to a first-order Markov process. To calculate an appropriate p-value for a test of linearity we propose a bootstrap procedure, which allows for general forms of heteroscedasticity. The performance of the bootstrap is checked by means of a Monte Carlo simulation. Our study concerns the USA. We find that cyclical shocks appear to play an important role on the observed persistence of output. [ABSTRACT FROM AUTHOR]

The relationship between stock prices and real estate prices has been the subject of substantial debate in both the academic and practitioner literatures. Existing studies have focused on the time series of stock and real estate returns using data from a single country, such as the U.S. By necessity, these studies examine return and price changes over short intervals, creating a bias when property values are smoothed from year to year. Using data from 17 different countries over 14 years, this paper examines the relation between stock returns and changes in property values and rents. Consistent with other country-specific studies, we find that, with the exception of Japan, the contemporaneous relation between yearly real estate price changes and stock returns is not statistically significant. However, when the data are pooled across countries and when we look at longer measurement intervals, a significant relation between stock returns and both rents and value changes becomes apparent. Real estate prices are also found to be significantly influenced by GDP growth rates and provide a good long-term hedge against inflation but a poor year-to-year hedge. [ABSTRACT FROM AUTHOR]

Studies of the predictive ability of the Federal Reserve's Beige Book for aggregate output and employment have proven inconclusive. This might be attributed, in part, to its irregular release schedule. We use a model that allows for data sampling at mixed frequencies to analyze the predictive power of the Beige Book. We find that the Beige Book's national summary and District reports predict GDP and aggregate employment and that most District reports provide information content for regional employment. In addition, there appears to be an asymmetry in the predictive content of the Beige Book language. [ABSTRACT FROM AUTHOR]

We use counterfactual experiments to investigate the sources of the large volatility reduction in US real GDP growth in the 1980s. Contrary to an existing literature that conducts counterfactual experiments based on classical estimation and point estimates, we consider Bayesian analysis that provides a straightforward measure of estimation uncertainty for the counterfactual quantity of interest. Using Blanchard and Quah's (1989) structural VAR model of output growth and the unemployment rate, we find strong statistical support for the idea that a counterfactual change in the size of structural shocks alone, with no corresponding change in the propagation of these shocks, would have produced the same overall volatility reduction as what actually occurred. Looking deeper, we find evidence that a counterfactual change in the size of aggregate supply shocks alone would have generated a larger volatility reduction than a counterfactual change in the size of aggregate demand shocks alone. We show that these results are consistent with a standard monetary VAR, for which counterfactual analysis also suggests the importance of shocks in generating the volatility reduction, but with the counterfactual change in monetary shocks alone generating a small reduction in volatility.

The article focuses on the consistency or conflict in Organisation for Economic Co-operation and Development (OECD) agricultural trade and aid policies in the U.S. Study shows that the negative effects of agricultural aid on growth in measured agricultural gross domestic product (GDP) per worker outbalance the positive effects. It was found out that the estimated aid coefficients are negative and statistically significant. This negative aid effect could be attributed to induced reductions in local market prices of commodities whose production increases as a consequence of aid. On the other hand, the strong positive effect of the degree of overlap between a developing country's crop planting patterns.

To what extent can information-technology led improvements in inventory management account for the apparent moderation of economic fluctuations in the United States since the mid-1980s? We argue that changes in inventory dynamics played a reinforcing—rather than a leading—role in the reduction of output volatility. Since the mid-1980s, inventory dynamics have changed in a manner consistent with a faster resolution of inventory imbalances. However, these changes appear to be a consequence of changes in the response of industry-level sales and aggregate economic activity to monetary policy shocks. Our results suggest that it is the interaction between the changes in inventory behavior at the industry level and the macroeconomic environment—where the latter likely includes changes in the conduct of monetary policy and the responses of the economy to policy disturbances—rather than any single factor, that has contributed importantly to the observed decline in economic volatility.

Objective: To provide guidance on selecting the most appropriate price index for adjusting health expenditures or costs for inflation.Data Sources: Major price index series produced by federal statistical agencies.Study Design: We compare the key characteristics of each index and develop suggestions on specific indexes to use in many common situations and general guidance in others.Data Collection/extraction Methods: Price series and methodological documentation were downloaded from federal websites and supplemented with literature scans.Principal Findings: The gross domestic product implicit price deflator or the overall Personal Consumption Expenditures (PCE) index is preferable to the Consumer Price Index (CPI-U) to adjust for general inflation, in most cases. The Personal Health Care (PHC) index or the PCE health-by-function index is generally preferred to adjust total medical expenditures for inflation. The CPI medical care index is preferred for the adjustment of consumer out-of-pocket expenditures for inflation. A new, experimental disease-specific Medical Care Expenditure Index is now available to adjust payments for disease treatment episodes.Conclusions: There is no single gold standard for adjusting health expenditures for inflation. Our discussion of best practices can help researchers select the index best suited to their study. [ABSTRACT FROM AUTHOR]

Recent contributions to the theoretical and empirical trade literature emphasize the channels by which exporting occurs and the duration and survival rates of trade relationships. However, for agricultural trade, few studies have considered the factors affecting export survival. This article identifies factors affecting the duration of fresh fruit and vegetable exports to the U.S. market, including U.S. sanitary and phytosanitary (SPS) policy regulations. The main findings can be summarized as follows. First, our preferred model with exporter binary variables indicates that changes in U.S. commodity prices and exporter gross domestic product have the largest impact, whereas U.S. production variability and exporter experience have the lowest impacts on the hazard rate of export duration. Second, SPS treatment requirements have persistent impacts on trade duration. Water treatment requirements quadruple the average hazard rate in the first year of a spell of service, and while the hazard rate does diminish over time, it is still nearly three times the average hazard rate, even after the fourth year of the spell of service. Similarly, a combination treatment of fumigation and cold treatment/refrigeration more than triples the average hazard rate in the first year of the spell of service, but this effect diminishes more quickly over time.

We examine the implications of government size for macroeconomic volatility in a standard New-Keynesian model with multiple shocks. Larger government size mitigates volatility arising from technology, preference, mark-up and monetary policy shocks, but amplifies that emanating from expenditure shocks. The degree of mitigation-amplification varies with the size of government, which opens up the possibility of a non-monotone relationship between volatility and government size. When we estimate the model on US data we find that the relationship is negative around the current US size, but it could eventually turn positive as the ratio of government spending to GDP increased. The location of the turning point in this relationship depends mainly on the type of private expenditure crowded out by higher government spending and on the degree of price stickiness.

Research and development (R&D) has a large effect on both state output and total factor productivity in the long run. Our estimates for the private sector of the U.S. states from 1963 to 2007 show that the R&D elasticity averages 0.056-0.143. The implied returns to state Gross Domestic Product (GDP) from R&D spending are 82-211%. There are also positive R&D spillovers, with 70-80% of the total returns accruing to other states. We also find that states with more human capital have higher own- and other-R&D elasticities, and those in lowest tier of economic development have the least own-state R&D elasticity but the highest other-R&D elasticity. In addition, we find that the positive effect of R&D spillovers across states is larger when we consider R&D spillovers across states based on economic similarity of R&D across sectors.

Use of wood biomass for energy results in carbon (C) emissions at the time of burning and alters C stocks on the land because of harvest, regrowth, and changes in land use or management. This study evaluates the potential effects of expanded woody biomass energy use (for heat and power) on net C emissions over time. A scenario with increased wood energy use is compared with a dynamic business-as-usual scenario where wood energy use is driven by its historical relationship with gross domestic product. At the national level, we projected that up to 78% of increased cumulative C emissions from increased wood burning and up to 80% of increased cumulative radiative forcing would be offset over 50 years by change in forest area loss, biomass regrowth on land, C storage in harvested wood products, and C in logging slash left in forests. For example, forest area is projected to decline in both scenarios, but 3.5 million hectares more are retained in the high wood energy-use case. Projected C offsets over a 50 year period differed substantially by US region (16% in the North, 50% in the West, and 95% in the South) not only because of differences in forest regrowth and induced investment in retaining and planting forest, but also because of shifts in competitive advantage among regions in producing various wood products. If wood systems displace coal systems that have 75% of the C emissions of wood energy systems per unit energy, then the nationwide net C emissions offset would be reduced to 71-74%. If displacing natural gas systems that have 40% of the level of wood bioenergy emissions per unit energy, the nationwide net C emissions offset would be 46-52%. [ABSTRACT FROM AUTHOR]

Overview: Dollar surge brings mixed consequences The strengthening dollar is now becoming a significant factor for global growth and our forecasts. The tradeweighted dollar is up 2.5% over the last month and over 12% on a year ago., Driving the latest rise are growing expectations of US rate hikes while monetary policy in many other major economies is headed in the opposite direction., The beginning of ECB QE has prompted a further slide in bond yields and the euro - which at 1.06/US$ is on course to fulfill our forecast of near-parity by year-end. Weak data in Japan also raises the chance of a further expansion of QE there later this year., We remain relatively positive about the advanced economies: we forecast G7 GDP growth at 2.2% for 2015 and 2.3% next. This month we have revised up German growth for 2015 to 2.4% - a four-year high., Robust US growth and a strong dollar are good news for the advanced economies. US import volume growth firmed to over 5% on the year in January, while the dollar surge potentially boosts the share of other advanced countries in this growing market., But for the emerging economies the picture is mixed. A stronger US may boost exports, but rising US rates are pulling capital away: there has been a slump in portfolio inflows into emergers in recent months. Emerging growth may also suffer from higher costs of dollar funding and a rising burden of dollar debt as currencies soften - the more so if US rates rise faster than markets expect., Moreover, emergers are also under pressure from a slowing China. Chinese import growth has been weak of late and commodity prices remain under downward pressure. A notable casualty has been Brazil, which we have downgraded again this month - GDP is expected to slump 1.1% this year., Emerging GDP growth overall is expected to slip to 3.7% this year, the lowest since 2009. And excluding China, emerging growth will be only 2.2% - the same as the G7 and the worst performance relative to the advanced economies since 1999. [ABSTRACT FROM AUTHOR]

We use a gravity model of migration and alternative estimation strategies to analyze how income differentials affect the flow of immigrants into U.S. states using annual data from the American Community Survey. We add to existing literature by decomposing income differentials into short- and long-term components and by focusing on newly arrived less-educated immigrants between 2000 and 2009. Our sample is unique in that the vast majority of our observations take zero values. Models that include observations with zero-flow values find that recent male immigrants respond to differences in (short-term) GDP fluctuations between origin countries and U.S. states, and perhaps to (long-term) trend GDP differences as well. More specifically, GDP fluctuations pull less-educated male immigrants into certain U.S. states, whereas GDP trends push less-educated male immigrants out of their countries of origin. Effects for less-educated women are less robust, as GDP coefficients tend to be much smaller than for men. [ABSTRACT FROM AUTHOR]

We argue that financial market development contributed to the rise in the skill premium and residual wage inequality in the United States since the 1980s. We present an endogenous growth model with imperfect credit markets and establish how improving the efficiency of these markets affects modes of production, innovation, and wage dispersion between skilled and unskilled workers. The experience of U.S. states following banking deregulation provides empirical support for our hypothesis. We find that wages of skilled workers increased by between 0.5% and 6.3% following deregulation while those of unskilled workers fell by between 3.5% and 8.7%. Similarly, residual (or within-group) inequality increased; the 90-50 percentile ratio of residuals from a Mincerian wage regression and their standard deviation increased by 4.2% and 1.7%, respectively.

Stabilization policies frequently aim to boost spending as a means to increase gross domestic product. Spending does not necessarily translate into production, however, especially when inventories are involved. We look at the 'cash-for-clunkers' program that helped finance the purchase of nearly 700,000 vehicles in 2009. An analysis of auto sales and production movements reveals that the program did prompt a large spike in sales. But the program had only a modest and fleeting impact on production, as inventories buffered the movements in sales. These findings suggest caution in judging the efficacy of such policies by their impact on spending alone. [ABSTRACT FROM AUTHOR]

The welfare gain to consumers from the introduction of personal computers (PCs) is estimated. A simple model of consumer demand is formulated that uses a slightly modified version of standard preferences. The modification permits marginal utility, and hence total utility, to be finite when the consumption of computers is zero. This implies that the good will not be consumed at a high enough price. It also bounds the consumer surplus derived from the product. The model is calibrated/estimated using standard national income and product account data. The welfare gain from the introduction of PCs is 2%-3% of consumption expenditure. [ABSTRACT FROM AUTHOR]

This article studies the dynamic relationship between premiums and losses on the U.S. property-casualty insurance market, accounting for the external impacts of GDP and interest rate. Compared to the existing literature, the present work innovates in that the dynamic relationships between premiums, losses, GDP, and interest rate are studied in a cointegration framework, single-equation and vector approach, involving the long- and short-run dynamics. The results suggest a stable long-run equilibrium between premiums, losses, and general economy. On short term, the premiums adjust quickly and significantly to the long-term disequilibrium and have a strong autoregressive behavior. External factors contribute to explain the dynamics of premiums. [ABSTRACT FROM AUTHOR]

The article presents an outlook on the economic conditions of countries around the world. The default in Greece has been cited as the reason for the expected decline in gross domestic product (GDP) growth in the eurozone in 2012. It discusses the economic indicators of the U.S., including unemployment rate and Institute of Supply Management (ISM) manufacturing index. It offers forecasts on GDP and industrial output of Japan, as well as the eurozone countries.

The article reports on the global economic outlook that has worsened as of October 2011. It states that world gross domestic product (GDP) will rise by 2.8% in 2011 and in 2012, but will entail heavy downside risks which include an expansion of the Eurozone debt crisis, a possible new U.S. recession and an adverse impact on emerging economies. On the upside, credible plans to solve fiscal problems and lower commodity prices would reportedly stimulate corporate investment and hiring.

We provide new evidence on patterns of structural change in advanced economies, reconsidering the stylised facts put forward by , , and . Since 1980, the services sector has overwhelmingly predominated in the economic activity of the European Union, Japan, and the US, but there is substantial heterogeneity among services. Personal, finance, and business services have low productivity growth and increasing shares in employment and GDP. By contrast, shares of distribution services are constant, and productivity growth is rapid. We find that the labour share in value-added is declining, while the use of ICT capital and skilled labour is increasing in all sectors and regions. [ABSTRACT FROM AUTHOR]

We estimate oil price risk exposures of the U.S. oil and gas sector using the Fama-French-Carhart's four-factor asset pricing model augmented with oil price and interest rate factors. Results show that the market, book-to-market, and size factors, as well as momentum characteristics of stocks and changes in oil prices are significant determinants of returns for the sector. Oil price risk exposures of U.S. oil and gas companies in the oil and gas sector are generally positive and significant. Our study also finds that oil price risk exposures vary considerably over time, and across firms and industry subsectors. [ABSTRACT FROM AUTHOR]

We study the determinants of the cyclical behavior of banks' price-cost margins in the United States banking sector, using time series quarterly data for the period 1979-2005. We contribute to the literature by building an empirical model of the countercyclical behavior of these margins first documented by . Doing so we are able to explore potential explanations for this behavior, and to show that margins are consistently countercyclical, even after controlling for the effects of credit risk and monetary policy. As a mechanism for the propagation of aggregate shocks, the countercyclical nature of margins in banking can provide additional support to stabilization policy.

The Federal Reserve Greenbook forecasts of real GDP, inflation and unemployment are analysed for the period 1974–1997. We consider whether these forecasts exhibit systematic bias, and whether efficient use is made of information, that is, whether revisions to these forecasts over time are predictable. Rather than analyse the forecasts separately for each horizon of interest, we discuss and implement methods that pool information over horizons. We conclude that there is evidence of systematic bias and of forecast smoothing of the inflation forecasts. Copyright © 2007 John Wiley & Sons, Ltd. [ABSTRACT FROM AUTHOR]

Using forecasts from Consensus Economics Inc., we provide evidence on the efficiency of real GDP growth forecasts by testing whether forecast revisions are uncorrelated. As the forecast data used are multi-dimensional—18 countries, 24 monthly forecasts for the current and the following year and 16 target years—the panel estimation takes into account the complex structure of the variance–covariance matrix due to propagation of shocks across countries and economic linkages among them. Efficiency is rejected for all 18 countries: forecast revisions show a high degree of serial correlation. We then develop a framework for characterizing the nature of the inefficiency in forecasts. For a smaller set of countries, the G-7, we estimate a VAR model on forecast revisions. The degree of inefficiency, as manifested in the serial correlation of forecast revisions, tends to be smaller in forecasts of the USA than in forecasts for European countries. Our framework also shows that one of the sources of the inefficiency in a country's forecasts is resistance to utilizing foreign news. Thus the quality of forecasts for many of these countries can be significantly improved if forecasters pay more attention to news originating from outside their respective countries. This is particularly the case for Canadian and French forecasts, which would gain by paying greater attention than they do to news from the USA and Germany, respectively.

This article finds evidence that ideas and innovation are a key force explaining postwar growth in the U.S. economy. Utilizing data on patents issued since 1851, I construct a measure of the growth rate of knowledge. Capital stock estimates, human capital estimates, and real gross domestic product per worker growth rates are combined with the knowledge growth series to construct a time series test of endogenous innovation growth models. The results support the endogenous innovation approach but suggest that the accumulation of the per worker capital stock and changes in average human capital per worker are at least as important.

The question of how the level of development affects revolutionary support in society is of fundamental importance. One approach to provide an answer has been to study the relationship between actual civil conflict and income at the national level. This article takes a different approach. It uses microdata sets based on surveys of revolutionary support across one-quarter of a million people and identifies how the responses vary with their incomes. We find that a rise in GDP of $US 1,600 per capita in 2001 values decreases the chances of supporting revolt by 2.4 percentage points which represents a 41% drop in the proportion of people wanting a revolution. For a person who jumps from the bottom to top income quartile within their country, the probability declines by a similar amount. The results are robust to controlling for country and year effects, country-specific time trends and take account of the potential endogeneity of GDP. [ABSTRACT FROM AUTHOR]

We reconsider the out-of-sample forecasting ability of a large number of financial variables with respect to real output growth over the 1985:1-1999:4 period We show that models including financial variables display almost no forecasting ability relative to an autoregressive benchmark model over this period according to a mean squared forecast error metric. However, tests based on forecast encompassing indicate that many financial variables do, in fact, contain information that is useful for forecasting real output growth over the 1985:1-1999:4 out-of-sample period. Our results suggest that the extant literature exaggerates the demise of the forecasting power of financial variables with respect to real activity since the mid-1980s. [ABSTRACT FROM AUTHOR]

International calls include consumption and financial externalities. Theoretical analysis predicts that the volume of outbound and inbound calls is a function of originating-country price ("own-price") and terminating-country price ("cross-price"). Analysis of annual data for minutes of calling between the US and 17 West European countries from 1979 to 1986 reveals negative own-price effects in both directions, with inbound calls more elastic. Cross-price effects are generally not statistically significant. The findings are consistent with arbitrage and call-externality motivation that cancel each other. Level of GDP, number of telephones, and telex prices are statistically significant. [ABSTRACT FROM AUTHOR]

The article presents an economic outlook for the U.S. The American economy was manifesting signs of strains even before the financial crisis heightened in mid-September 2008. With the freeze in the credit markets, solid companies are not able to borrow in the commercial credit market to finance their operations, the risk to the real economy was severe. Analysts expect consumer spending to drop again in the fourth quarter of 2008 and in the first quarter of 2009. Overall gross domestic product (GDP) is expected to drop 1.0 percent in the fourth quarter of 2008.
