Abstract: Corruption has fierce impacts on economic and societal development and is subject to a vast range of institutional, jurisdictional, societal, and economic conditions. It is this paper's aim to provide a reassessment and a comprehensive state‐of‐the‐art survey of existing literature on corruption and its causes and effects. A particularly strong focus is put on presenting and discussing insights resulting from empirical research and contrasting recent with older findings. [ABSTRACT FROM AUTHOR]

Abstract: Despite phenomenal technological progress and exponential growth in computing power, economic growth remains comparative sluggish. In this paper, we investigate two core issues: (1) is there really no connection between ICT and national economic growth? and (2) what factors moderate the ICT–growth relationship? We apply meta‐regression analysis to 466 estimates drawn from 59 econometric studies that explore the Solow or Productivity Paradox that there is little impact of ICT on economic growth and productivity. We explore the differential impact of ICT on developed and developing countries and the differential impact of different types of ICT: landlines, cell phones, computer technology and Internet access. After accommodating potential econometric misspecification bias and publication selection bias, we detect evidence that ICT has indeed contributed positively to economic growth, at least on average. Both developed and developing countries benefit from landline and cell technologies, with cell technologies’ growth effect approximately twice as strong as landlines. However, developed countries gain significantly more from computing than do developing countries. In contrast, we find little evidence that the Internet has had a positive impact on growth.

Drawing on studies on the economics of conflict, this paper reviews the literature on maritime and territorial disputes; and it examines an array of economic implications associated with territorial and maritime disputes. These include adverse effects on certain economic and development outcomes arising from possible armed confrontation, with some of these possibly lingering in the aftermath of conflict. There are also various economic disruptions and costs associated with these disputes, emphasizing how they also affect the livelihoods of resource users in the disputed areas. A clearer understanding of these economic links could help inform and motivate policymakers on mitigating the risks of conflict. Based on the review of evidence herein, the economic implications of conflict in terms of foregone average trade among the country pairs considered in the West Philippine Sea/South China Sea (in 1985 dollars) – which differ in important ways but hint at some common channels of impact – could range from US$ 909.3 million to US$ 98.8 billion. More broadly, the impacts on a disrupted global production chain can easily amplify these results even further, affecting global growth prospects for many decades, according to experience.

Many economists have long held that market failures create a gap between social and private returns to research and development (R&D), thereby limiting private incentives to invest in R&D. However, this common belief that firms significantly underinvest in R&D is increasingly being challenged, leading the rationale behind public support for private R&D to be questioned. In this paper, we attempt to clarify the perspectives of two sources: the theoretical literature on endogenous growth, and its recent developments in integrating a geographical dimension, and the empirical literature that measures the social returns to R&D in relation to the private returns. Ultimately, we are able to clearly distinguish among different types of market failures and compare their relative impact on the gap between the private and social returns to R&D. Two main conclusions are reached. First, systematic firm underinvestment in R&D is not demonstrated. Second, even though instances of underinvestment do occur, they are mainly explained by surplus appropriability problems rather than by knowledge externalities. This suggests the need for a new policy mix that employs more demand-oriented instruments and is more concentrated on identifying efficient allocations among activities rather than merely increasing global private R&D investment.

The so‐called "new growth theory" is characterized by the now Nobel Prize winning insight that ideas are a nonrival input to and output from endogenous investment in innovation. Nonrivalry implies increasing returns to scale, but this also unintentionally creates an empirically disputed scale effect that a growing population implies an ever‐increasing growth rate. Empirical evidence supports fully‐endogenous growth without scale effects, but theoretical issues sustain the decades‐long dispute over exactly how to negate the scale effect. This article surveys theoretical approaches to resolving the scale effect and shows how four generations of endogenous growth theory are defined by the maturing of modeling techniques for constraining increasing returns. The synthesis suggests that the dispute over scale effects is really a narrative about how the powerful application of increasing returns has followed a standard theoretical development pattern. This implies that a fourth generation is now emerging that negates the scale effect while retaining fully‐endogenous growth without relying on assumptions of linearity. Instead, the market response to excessive increasing returns to innovation constrains explosive growth by expanding the market, rather than by a linear assumption. This latest class of endogenous growth models may be the final chapter to resolving the long‐running dispute. [ABSTRACT FROM AUTHOR]
