Migration Policy in a Small Open Economy with a Dual Labor Market

The paper uses a two–sector efficiency–wage model to analyze the consequences of immigration for a small open economy with a dual labor market. Immigrants are characterized by an (exogenous) return probability. Legal regulations impose preferential hiring of natives or "old" immigrants. As a result, there is sectoral segregation between natives and immigrants, leading to discrimination of the type equal pay for equal work,but unequal "work." In the short run (with sector–specific capital), immigration has a positive first–order impact on natives' welfare if migration policy favors segregation through high return rates or restrictive hiring practices ("guest–worker system"). In the long run, its effect is only determined by factor intensities (2 ¥ 2 model). Finally, the improved integration of migrants yields efficiency gains and improves aggregate welfare of all residents.     

The curse of natural resources in the transition economies*

The curse of natural resources is a well‐documented phenomenon for developing countries. Economies that are richly endowed with natural resources tend to grow slowly. Among the transition economies of the former ‘Eastern Bloc’, a similar pattern can be observed. This paper shows that a large part of the variation in growth rates among the transition economies can be attributed to the curse of natural resources. After controlling for numerous other factors, there is still a strong negative correlation between natural resource abundance and economic growth. Among the transition economies the prime reasons for the curse of natural resources were corruption and a neglect of basic education. In order to overcome the curse of natural resources and move to a sustainable path of development, the resource abundant transition countries should fight corruption and ensure that their resource revenues are invested in human capital or the preservation of natural capital.

Credit Supply and Demand and Business Investment

Abstract
The article explores the lending behaviour of financial intermediaries over the business cycle in the light of theories emphasising agency costs. During a credit crunch loans from financial intermediaries are unobtainable at any price, and so credit may have a causal influence over economic activity. Tests of this do not find evidence of credit constraints following financial deregulation. However, since both loan supply and demand are driven by forward-looking variables, business credit is a useful leading indicator of nominal investment .     

Trust over time in exchange relationships: Meta‐analysis and theory

A common premise in prior research is that trust increases over time in relationships. Through a meta‐analysis of 39 studies, we find that the bivariate correlation between trust and relationship duration (1) is on average positive and small, and (2) varies significantly across studies indicating the presence of unobserved moderators. We therefore build a theoretical framework to specify four different mechanisms—initial bias correction, change in relationship value, identification, and trust‐based selection—that may affect the development of trust. We then argue that the relative strength of these mechanisms should influence whether trust increases, remains constant, or decreases over time. © 2013 The Authors.

Dishonesty and charitable behavior

We examine in the laboratory how having the opportunity to donate to a charity in the future affects the likelihood of engaging in dishonest behavior in the present. We also examine how charitable donations are affected by past ethical choices. First, subjects self-report their performance on a task, which provides them with an opportunity for undetected cheating. In the second stage they can donate some of the money earned in the first stage to a charity. Only subjects in the treatment group know about the opportunity to donate in the second stage. We find that more subjects cheat if they know they can donate some of the money to charity. We also find that subjects in treatment end up donating less to charity and that both honest and dishonest subjects donate less in treatment. We propose a new hypothesis that explains these results: past violations of social norms numb one’s conscience, leading to more antisocial behavior.     

Oil crisis,energy-saving technological change and the stock market crash of 1973–74

The market value of U.S. corporations was nearly halved during the oil crisis of 1973–74. In this paper, we investigate the hypothesis that the sharp rise in energy costs during this period resulted in the obsolescence of firms' existing capital and reduced their market value. To quantify this obsolescence channel of the energy crisis, we simulate a calibrated dynamic general equilibrium model, where firms adopt energy-saving technologies along with the rise in energy prices, and the value of their installed capital falls due to investment irreversibility. We find that this channel can account for a third of the decline in Tobin's q observed in the data. Separately, we consider the role of investment subsidies extended by the government during this period to expedite the adoption of energy-saving technologies. This extension of the model can account for more than half of the decline in q. We also find empirical support for the capital obsolescence channel in cross-sectional regressions, where we show that the sectoral variation in the decline of energy use following the crisis is significant in explaining the sectoral variation in the drop of market values.     

Ökonomische Folgen eines Atomausstiegs in Deutschland

Nach der Atomkatastrophe in Fukushima hat die Bundesregierung beschlossen, bis Mitte Juni die Zukunft der Atomenergie in Deutschland zu überdenken. Dabei k?nnen unterschiedlich weitgehende Szenarien betrachtet werden. Sie reichen von einer Rücknahme der im letzten Herbst beschlossenen Laufzeitverl?ngerung bis hin zum vollkommenen Ausstieg aus der Kernkraft. Die Autoren vertreten grunds?tzlich die Auffassung, dass die wirtschaftlichen Folgen eines Atomausstiegs zu bew?ltigen sind. Mit einer Steigerung der Energiepreise muss allerdings gerechnet werden — wie deutlich diese ausf?llt, und welche Referenzwerte herangezogen werden müssen, h?ngt von vielen Faktoren ab.
