Globalisation and union opposition to technological change

Trade unions have a rational incentive to oppose the adoption of labour-saving technology when labour demand is inelastic and unions care much for employment relative to wages. Trade liberalisation typically increases trade union technology opposition. These conclusions are reached in a model of unionised international duopoly with two-way trade. We also find that the incentive for technology opposition is stronger in the more technologically advanced country and in the country with the larger home market, complementing earlier explanations for technological catch-up and leapfrogging.     

Elective Stock Dividends and REITs: Evidence from the Financial Crisis

In response to the recent financial crisis, the U.S. Government introduced new rules which allow Real Estate Investment Trusts (REITs) to issue elective stock dividends (ESDs), i.e., noncash dividends, to satisfy their distribution requirements. The purported goal of these rules was to provide temporary relief to REITs facing cash flow problems. We investigate how the introduction of these rules affects dividend policy of REITs. Surprisingly, we document that only 17 REITs chose to issue elective stock dividends. We examine the characteristics of these REITs and find that their cash flows are similar to REITs that do not select these dividends. This suggests that cash flow problems are unlikely to be the primary determinant of the ESD issuance decision. Instead, our findings indicate the decision to pay ESDs is related to the level of loans that are close to maturity, REIT size, growth prospects and poor performance during the financial crisis. Furthermore, we find that the same factors determine the ratio, amount and frequency of stock dividends issued by these REITs. We also examine the response of shareholders to ESDs announcements and find positive abnormal returns surrounding these dividend announcements.     

China in Global Economic Governance

China has made contradictory claims about its attitude toward the existing international order. Is China a “responsible stakeholder” in the existing international regimes? Or has China been a new type of great power seeking to reform the existing world order, making it more friendly toward the global South? In this article, we look beyond Chinese rhetoric and examine China's behavior in global economic governance. A comparison with other emerging powers and traditional major powers shows that China has been actively involved in global economic governance. But, thus far, China has not exercised substantive leadership nor has it pushed hard for change to benefit the developing countries. The level of its support of the current regimes varies across issue areas and is primarily driven by its changing economic interest.     

Short-time work—Some long-run implications

This paper outlines a simple model to examine some long-run implications of short-time work schemes (STWs) on labor market performance and welfare. It is not clear that STWs reduce unemployment as the induced wage push discourages job creation.     

Second thoughts on free riding

We use the strategy method to classify subjects into cooperator types in a large-scale online Public Goods Game and find that free riders spend more time on making their decisions than conditional cooperators and other cooperator types. This result is robust to reversing the framing of the game and is not driven by cognitive ability, confusion, or natural swiftness in responding. Our results suggest that conditional cooperation serves as a norm and that free riders need time to resolve a moral dilemma.     

Estimating SUR system with random coefficients: the unbalanced panel data case

A system of regression equations for analyzing panel data with random heterogeneity in intercepts and coefficients, and unbalanced panel data is considered. A maximum likelihood (ML) procedure for joint estimation of all parameters is described. Since its implementation for numerical computation is complicated, simplified procedures are presented. The simplifications essentially concern the estimation of the covariance matrices of the random coefficients. The application and ‘anatomy’ of the proposed algorithm for modified ML estimation are illustrated by using panel data for output, inputs and costs for 111 manufacturing firms observed up to 22 years.     

Migration and Americanization: The special case of Belgian economics*

One of the distinguishing features of Belgian economics is that, from the early 1920s, so many of Belgium's best economists pursued postgraduate studies at top American universities, a case of ‘temporary’ migration. This was made possible by the fellowships granted by the Commission for Relief in Belgium, a legacy of the First World War. After a stay in the US of a few years, most returned to Belgium. However, they maintained strong links with the US. Also, they tried to recreate in Belgium the most valuable elements of their American experience. It would lead to a strong and early Americanization of Belgian economics. Moreover, they were at the forefront of several initiatives to organize economics on a European scale, such as the European Economic Review and the European Economic Association.     

Sponsorship effect metric: assessing the financial value of sponsoring by comparisons to television advertising

Since sponsoring is an increasingly important marketing communication medium, it is important for managers to know whether their sponsorships are giving a good financial return relative to other communication alternatives. Although several “rules of thumb” are commonly used in the industry for converting sponsorship exposure time into television advertising equivalent values, this research is the first to empirically test them by means of two experiments employing realistic stimuli and representative samples. Across 6 stimuli brands, study 1 finds that an average of 127 s of sponsor logo exposure achieves the same effects as a 30 s TV ad, but variance around this figure is high and depends on a variety of factors such as communication goal, sponsor fit, type of exposure, and whether the sponsor is a known brand. Study 2 finds that combining sponsoring with television advertising does increase the effects of sponsoring, although effects vary widely depending on the context, but even in the best case the increase is not supportive of the high levels of advertising suggested by many industry experts. Overall, the findings will allow managers to more confidently assess the financial value of their sponsorship investments.     

Secondary upwelling instabilities developed in high Rayleigh number convection: Possible applications to hot spots

We have conducted numerical experiments for mantle convection in an axisymmetrical spherical-shell geometry from Rayleigh numbers ranging from three million to 10 billion for a purely basal heating configuration. We focus on the development of secondary instabilities developed from plumes and compare them with laboratory experiments by Skilbeck and Whitehead (1978) and Whitehead, (1982). For Rayleigh numbers between around thirty million to one billion, a string of these secondary instabilities can develop from a single plume. Analysis of the spectrum of wavelength associated with the fold instabilities shows that there is a window in the Rayleigh number between around ten million and one bilion where these secondary folding instabilities would develop. These results, when applied to the upper mantle, may explain the formation of hot-spots in a turbulently convecting upper-mantle with a Rayleigh number greater than ten million.
