PROPERTIES OF OPTION PRICES IN MODELS WITH JUMPS

We study convexity and monotonicity properties of option prices in a model with jumps using the fact that these prices satisfy certain parabolic integro–differential equations. Conditions are provided under which preservation of convexity holds, i.e., under which the value, calculated under a chosen martingale measure, of an option with a convex contract function is convex as a function of the underlying stock price. The preservation of convexity is then used to derive monotonicity properties of the option value with respect to the different parameters of the model, such as the volatility, the jump size, and the jump intensity.     

Does corruption increase emerging market bond spreads?

We study the relationship between corruption and borrowing costs for governments and firms in emerging markets. Combining data on bonds traded in the global market with survey data on corruption compiled by Transparency International, we show that countries that are perceived as more corrupt must pay a higher risk premium when issuing bonds. The global bond market ascribes a significant cost to corruption: an improvement in the corruption score from the level of Lithuania to that of the Czech Republic lowers the bond spread by about one-fifth. This is true even after controlling for macroeconomic effects that are correlated with corruption. We find little evidence that investors became more sensitive to corruption in the wake of the Asian financial crisis.     

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.     

Public management reform in Denmark

Abstract

This article discusses public management reform in Denmark. First, the institutional features of the Danish public sector are introduced. Danish ministries enjoy a considerable amount of autonomy that makes central co-ordinated public management reform challenging. The second part of the article outlines the contents of public management reform and provides an overview of the major reform initiatives of the last three governments. Denmark's reforms are characterized as a mixture of strategies for modernization and marketization, but with most emphasis on the former rather than the latter. Together with successive governments, the Danish Ministry of Finance has argued strongly for efficiency, economy and effectiveness as key values and they have been institutionalized in modernization efforts. Denmark should now be considered a country where NPM reforms have taken a firm hold.
