Labour Mobility: An Adjustment Mechanism in Euroland? Empirical Evidence for Western Germany,France and Italy

We evaluate whether labour mobility is likely to act as a sufficient adjustment mechanism in the face of asymmetric shocks in Euroland. As no adequate data on cross-border migration are available, migration elasticities within nation states (Western Germany, France and Italy) are estimated and interpreted as upper bounds for cross-border migration elasticities between European nation states. Labour mobility is highest in Germany, followed by France and Italy. However, the accommodation of a shock to unemployment by migration takes several years. We conclude that labour mobility is unlikely to act as a sufficient adjustment mechanism to asymmetric shocks in Euroland.     

The Relevance of Responsibility to Ethical Business Decisions

This paper addresses researchers’ call for integrating workplace spirituality with organizational literature. This paper points out that self-interest transcendence is a common aspect in the workplace spirituality concept that emerged in the last decade and also in four OB concepts – transformational leadership, organizational citizenship behavior, organizational support, and procedural justice – that emerged in OB about two decades ago. Based on this common aspect of self-interest transcendence and the temporal precedence of these four OB concepts’ emergence, it indicates that these four OB concepts constitute a precursor of workplace spirituality. It places workplace spirituality in the larger context of OB␣and outlines the associated research and practice implications. The author also holds a lien on the position of professor at XLRI School of Business and Human Resources, India.     

The use of visual warnings in social marketing: The case of tobacco

Despite strong interest on the part of tobacco health practitioners, the effect of graphic warnings inserted on cigarette packs is unclear on several levels. First, the most effective themes for such messages have not been clearly identified by researchers. Second, no research has identified the ideal combination of self-efficacy and fear appeal warnings that should be inserted on cigarette packs, according to Protection Motivation Model principles. The exploratory study we conducted with French consumers to test the effectiveness of new graphic warnings proposed by the European Union in 2004 clearly demonstrates that visual messages, as opposed to text warnings, are more effective. This study also enabled us to identify the most effective themes of the European set: health warnings and social messages. Regarding future public health applications, if fear appeals are used, they need to be combined with self-efficacy and cessation support messages since they provoke avoidance reactions.     

Sentiment and stock returns: The SAD anomaly revisited

Widely-cited research by Kamstra et al. (2003) argues that changes in mood resulting from Seasonal Affective Disorder (SAD) drive changes in investor risk aversion and cause seasonal patterns in aggregate stock returns around the world. In this paper we reexamine the so-called SAD effect by replicating and extending Kamstra et al. (2003). We study the psychological underpinnings of the SAD hypothesis and show that the time-series predictions of the SAD model do not correspond to the seasonal patterns in depression found in the general population. We also investigate the cross-sectional prediction that SAD has a greater effect on stock markets in countries where SAD is more prevalent and find no relation between the prevalence of SAD and stock returns. Finally, we document that the SAD effect is mechanically driven by an overlapping dummy-variable specification and higher returns around the turn of the year.     

Spatial Aspects of ICT Development in Russia

The paper investigates the potentials of ICT in Russia for tackling the challenges of huge territory, strong regional disparities, segmentation of economic space and over-centralisation by Moscow. The Internet currently imposes a definite regional discrimination in Russia based on complex criteria, which are not limited to household incomes. After initial polarisation in Moscow and Saint Petersburg, Internet use is now concentrated in a dozen Russian regions, marking a shift to polycentric polarisation, but Internet service activities remain concentrated in Western Russia. A new wave of centrifugal trends is starting thanks to offshore outsourcing in software development, in which Russia is preferred to China and India.     

Evaluating wind-following and ecosystem services for hydroelectric dams in PJM

Hydropower can provide inexpensive, flexible fill-in power to compensate for intermittent renewable generation. Policies for hydropower dams maintain multiple services beyond electric generation, including environmental protection, flood control and recreation. We model the decision of a hydroelectric generator to shift some of its power production capacity away from the day-ahead energy market into a “wind-following” service to smooth the intermittent production of wind turbines. Offering such a service imposes both private and social opportunity costs. Since fluctuations in wind energy output are not perfectly correlated with day-ahead energy prices, a wind-following service will necessarily affect generator revenues. Seasonal wind patterns produce conflicts with the goal of managing rivers for “ecosystem services”—the maintenance or enhancement of downstream ecosystems. We illustrate our decision model using the Kerr Dam in PJM’s territory in North Carolina. We simulate the operation of Kerr Dam over a three-year period that features hydrologic variability from normal water years to extreme drought conditions. We use an optimization framework to estimate reservation prices for Kerr Dam offering wind-following services in the PJM market. Wind-following may be profitable for Kerr Dam at low capacity levels during some time periods if ecosystems services are neglected and if side payments, or reserves-type payments, are provided. Wind-following with ecosystem services yields revenue losses that typically cannot be recovered with reserves market payments. Water release patterns are inconsistent with ecosystem-services goals when Kerr Dam dedicates significant capacity to wind-following, particularly in drought years.     

Toward a North American Security Perimeter? Assessing the trade,FDI, and welfare impacts of liberalizing 9/11 security measures

This paper examines the trade, FDI, and welfare impacts of (liberalizing) 9/11 security measures at the Canada–US border. First, the study provides econometric estimates of the impact of post 9/11 security measures on bilateral (US–Canada) trade flows. Second, we compute sectoral tariff rates “equivalent” to the 9/11 security measures using these econometric estimates together with a three-region nine-sector general equilibrium model. Finally, we assess for both the Canadian and the US economies: 1) the (general equilibrium) impacts on trade, FDI, and welfare, of (liberalising) the 9/11 US security measures and 2) the economic impacts of a change of security paradigm toward a North American Security Perimeter within a Customs Union that would liberalize the Canadian and US 9/11 security measures at the Canada–US border and shift them at the external security perimeter.     

On the incidence of commissions in auction markets

We analyze the welfare consequences of an increase in the commissions charged by intermediaries in auction markets. Commissions are similar to taxes imposed on buyers and sellers, and standard economics suggests that both sellers and buyers are made worse off by the tax. However, we show that when the buyers' participation constraint binds and when sellers set optimal reservation prices, the level of commissions correlates to participation and reservation prices in such a way that participating buyers strictly gain from higher commissions.     

Did Hayek have a monetary theory of business cycles?

Joseph Schumpeter, a careful reader of Hayek, categorized Hayek??s theory of economic cycles as non-monetary. Almost every other source, including Hayek himself, categorized the theory as monetary. The issue turns on the concept of causality being used. The question of what causality concept to apply to complex phenomena has substantive implications for economic theory. A simple concept of causality, appropriate to the study of some physical phenomena, will mislead when applied to complex phenomena. We provide examples of errors in analysis that follow from the wrong choice of a causal paradigm.
