Global food demand,productivity growth,and the scarcity of land and water resources: a spatially explicit mathematical programming approach

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.     

You Don't Have to be German to be a "Hidden Champion"

The "hidden champions" among Germany's medium-sized companies are becoming a by-word for students of management. But do hidden champions exist outside Germany? What management processes distinguish them from other companies? And are there lessons from their success for other companies? This article, extracted from the author's forthcoming book, summarises his answers to these questions.     

Accounting for Investments in Human Capital: A Review

This paper provides an overview of the human capital literature, focusing on the firm's incentives and disincentives to invest in human capital and subsequently to account for the investments. The evidence suggests human capital investment decisions are intrinsically linked to the success of a business and ultimately to the probability of survival. However, disclosure is largely a voluntary choice by managers as there are few formal disclosure requirements. The conclusion from the evidence shows that the benefits to stakeholders of disclosing information relating to human capital investment are likely to outweigh the costs and suggests a wide range of topics for future research.

Is there a “Dark Side” to Monitoring? Board and Shareholder Monitoring Effects on M&A Performance Extremeness

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 .

China and Its Dollar Exchange Rate: A Worldwide Stabilising Influence?1

China is criticised for keeping its dollar exchange rate fairly stable when it has a large trade (saving) surplus. This criticism is misplaced in two ways. First, no predictable link exists between the exchange rate and the trade balance of an international creditor economy. Second, since 1995, the stable yuan/dollar rate has anchored China’s price level and facilitated counter cyclical fiscal policies that have smoothed its high real GDP growth at a remarkable 9 to 11 per cent per year. With its now greater GDP, China displaces Japan as the largest economy in East Asia – but with a much stronger stabilising influence on East Asian neighbours from its higher economic growth and more stable dollar exchange rate. Now, an ever larger China is an essential stabiliser for the world economy – as exemplified by its prompt and effective fiscal response to the global credit crunch of 2008–09. However, cumulating financial distortions – in China and the United States – threaten to undermine China’s growth and its stabilising influence on the rest of the world.     

Strukturelle Verzerrungen im Währungskrieg

Die chinesische W?hrungspolitik steht weltweit in der Kritik. Die Dollarbindung des Yuan hat sich jedoch als Stabilit?tsanker für die ostasiatische Region bew?hrt. Der globale Handel profi tiert von der stabilen Wirtschaftsentwicklung in dieser Region. Allerdings führt das Festhalten an einem real unterbewerteten Yuan zu Verzerrungen der Wirtschaftsstruktur bei China und seinen Handelspartnern.
