Measured in per cent of their Gross National Product (GNP), western industrialised countries currently spend far less on development aid than they did ten years ago. This is partly due to the very limited usefulness of the prevailing concept of development aid.  相似文献

Success in economic development is normally measured in terms of growth rates in gross national product, with little attention given to the accompanying increase in employment. However, growth can be more or less labor absorbing depending upon the technology introduced during industrialization. In this article the author states the case for intermediate technology along with examples of its application.  相似文献

In dealing with growing income inequality, economists and social scientists have ignored the interdependencies between economic performance, voter turnout and people’s psychological damages and social deprivations. This article emphasises the role of demography for the bargaining power of trade unions and employer associations. It demonstrates the concomitance of full employment and shrinking income inequality and, correspondingly high unemployment and growing income inequality. Due to the decrease in the size of the labour force in Germany since 2005, the gap between higher and lower incomes will soon become smaller, and many economic and social problems can be solved.  相似文献

While theory and evidence show that firms' competitive actions mediate the resource‐performance relationship, details of top managements' roles in shaping resource utilization choices have been underemphasized. We address this oversight by integrating top management team heterogeneity and any resulting faultline strength with the resource‐action‐performance model to investigate how TMT composition differentially affects the model's two linkages. Specifically, we argue that TMT heterogeneity positively affects the resource‐action linkage, yet negatively affects the action‐performance linkage. Moreover, when heterogeneity begets strong faultlines, all such positive effect is lost. Supportive evidence from the in‐vitro medical diagnostic substance manufacturing industry allows us to discuss how our findings contribute to upper echelons theory, as well as the emerging stream on resource utilization.

Agriculture is unique among economic sectors in the nature of impacts from climate change. The production activity that transforms inputs into agricultural outputs involves direct use of weather inputs (temperature, solar radiation available to the plant, and precipitation). Previous studies of the impacts of climate change on agriculture have reported substantial differences in outcomes such as prices, production, and trade arising from differences in model inputs and model specification. This article presents climate change results and underlying determinants from a model comparison exercise with 10 of the leading global economic models that include significant representation of agriculture. By harmonizing key drivers that include climate change effects, differences in model outcomes were reduced. The particular choice of climate change drivers for this comparison activity results in large and negative productivity effects. All models respond with higher prices. Producer behavior differs by model with some emphasizing area response and others yield response. Demand response is least important. The differences reflect both differences in model specification and perspectives on the future. The results from this study highlight the need to more fully compare the deep model parameters, to generate a call for a combination of econometric and validation studies to narrow the degree of uncertainty and variability in these parameters and to move to Monte Carlo type simulations to better map the contours of economic uncertainty.  相似文献

The EU has long viewed economic and institutional convergence as important goals, but the results thus far have been decidedly mixed, and there remain several open questions: How exactly should convergence be defined? How much convergence is necessary? What steps can be taken to improve convergence in the EU, and how can success be defined? Finally, how much convergence can be achieved by improving the economic performance in underperforming regions, and how can convergence in the form of harmonisation towards lower welfare levels be avoided?  相似文献

Research summary: W e investigate the effects of monitoring by boards of directors and institutional shareholders on merger and acquisition (M&A ) performance extremeness using a sample of M&A deals from 1997 to 2006. Both governance research and legal reforms generally have espoused a “raise all boats” view of monitoring. We instead investigate whether monitoring may serve as a double‐edged sword that limits CEO discretion to undertake both value‐destroying M&A deals and value‐creating ones. Our findings indicate that the relationship between monitoring and M&A performance is more complex than previously believed. Rather than “raising all boats” in a shift towards better M&A outcomes, monitoring instead is associated with lower M&A losses, but also with lower M&A gains . Managerial summary: M ergers and acquisitions (M&A s) are a quintessential corporate activity. There were $3.8 trillion worth of M&A deals in 2015, despite scholars and practitioners reporting that M&A s often perform poorly. We question the widespread belief that more vigilant monitoring by boards of directors and large shareholders will raise M&A performance, overall. Put differently, does monitoring constrain CEO s' discretion to pursue bad deals, while simultaneously encouraging them to pursue good ones? We find that monitoring limits both large M&A losses and large M&A gains. Contrary to widely held beliefs, our results indicate that constraining executives' ability to pursue value‐destroying M&A deals does not simultaneously encourage or enable CEO s to pursue value‐creating deals .

In the coming decades, an increasing competition for global land and water resources can be expected, due to rising demand for food and bio‐energy production, biodiversity conservation, and changing production conditions due to climate change. The potential of technological change in agriculture to adapt to these trends is subject to considerable uncertainty. In order to simulate these combined effects in a spatially explicit way, we present a model of agricultural production and its impact on the environment (MAgPIE). MAgPIE is a mathematical programming model covering the most important agricultural crop and livestock production types in 10 economic regions worldwide at a spatial resolution of three by three degrees, i.e., approximately 300 by 300 km at the equator. It takes regional economic conditions as well as spatially explicit data on potential crop yields and land and water constraints into account and derives specific land‐use patterns for each grid cell. Shadow prices for binding constraints can be used to valuate resources for which in many places no markets exist, especially irrigation water. In this article, we describe the model structure and validation. We apply the model to possible future scenarios up to 2055 and derive required rates of technological change (i.e., yield increase) in agricultural production in order to meet future food demand.  相似文献
