Cyclical fluctuations in the market economy have been the focus of attention of researchers for many years. Today, the process of reproduction is becoming cyclical, which is a problem of interest of all economic agents. The purpose of the article is to reveal the main causes of economic cycles, their nature and to show the effect of cyclical fluctuations on the production process and employment, as well as in the development of a new socio-economic society as a whole. The article shows the essence of each stage, their disadvantages and advantages, influence on the formation of a creatively developed person.

This paper aims to detail Frisch’s choice of setting the accelerator principle at the core of his impulse-propagation model (1933a), referred to as the “rocking horse model.” The innovative aspects of this model rest not only on the rise of macrodynamics regarding the equilibrium concept but also on the reformulation of business cycles in terms of production of capital goods. This is a deliberate choice, which relies on his work on business cycles started in 1927, and can be obviously traced back to his debate with John Maurice Clark and the American Institutionalists, but relies more deeply on a specific appropriation of Norwegian approach to this principle.

This report highlights recent economic updates in Bangladesh as of April 2015. Economic growth in Bangladesh was gaining momentum in the first half of FY15. Capacity utilization improved and investments were showing some signs of recovery. This growth was also job-friendly. The 12-monthly-moving average inflation decelerated from 7.6 percent in February 2014 to 6.8 percent in February 2015. The resilience of the Bangladesh economy continues to be tested by faltering political stability, weak global markets, and structural constraints. These are inhibiting the economy s income growth as well as progress on shared prosperity. Despite the emergence of a $1.3 billion deficit in the current account in the first seven months of FY15, the surplus in the overall balance of payments has been sustained, leading to continued accumulation of official foreign exchange reserves to prevent nominal exchange rate appreciation. Reserves are at a comfortable level at over 6 months of imports of goods and services. Fiscal policy has remained consistent with macroeconomic stability. Tax revenue growth has been weaker than targeted while expenditure have also been short due as usual to an implementation shortfall. The projected recovery in global growth, particularly in the United States and the Euro Zone, and continued softness in international commodity prices, bode well for Bangladesh. The country will need to restore political stability and implement faster structural reforms to capitalize on these opportunities. The potential GDP growth rate is on a declining path due to declining labor force growth and stagnant productivity growth, as well as the rate of capital accumulation. Raising the low Female Labor Force Participation (FLFP) rate offers on opportunity to boost the economy s potential growth rate. Moving forward, the biggest challenge remains ensuring durable political stability. This is a precondition for accelerated, inclusive, and sustainable growth.

A model of macroeconomic complementarity is used to assess causes of comovement in investment spending across nine sectors of the U.S. economy. It is hypothesized that the irreversibility and uncertainty of investment spending imply a greater role for investment linkages and aggregate factors in investment fluctuations compared with estimates for employment and output. For the average sector, past investment growth across all sectors, changes in aggregate demand, and a common factor account for two-thirds of the variance of investment growth. After accounting for aggregate demand, sectoral shocks explain 70% of the average sector’s innovations to investment growth.

Do all types of demand have the same effect on output? To answer this question, I estimate a cointegrated vector autoregressive (VAR) model of consumption, investment, and government spending on US data, 1955–2007. I find that: (1) economic growth can be decomposed into a short-run (transitory) cycle gravitating around a long-run (permanent) trend made of consumption shocks and government spending; (2) the estimated fluctuations are investment dominated, they coincide remarkably with the business cycle, and they are highly correlated with capacity utilization in both labor and capital; and (3) the long-run multipliers point to a large induced investment phenomenon and to a smaller, but still significantly positive, government spending multiplier, around 1.5. The results cover a lot of theoretical ground: Paul Samuelson’s accelerator principle, John Kenneth Galbraith’s stress on consumption and government spending, Jan Tinbergen's investment-driven business cycle, and Robert Eisner’s inquiries on the investment function. The results are particularly useful to distinguish between economic policies for the short and long runs, albeit no attempt is made at this point to inquire into the effectiveness of specific economic policies.
