An Econometric Analysis of Global Waste Paper Recovery and Utilization

The main purpose of this paper is to provide aneconometric analysis of the most importantdeterminants of inter-country differences inwaste paper recovery and utilization rates. Byemploying pooled time series and cross-sectiondata over 49 countries worldwide and sevenyears, the paper concludes that relative wastepaper recovery and use depend largely onlong-standing economic factors such aspopulation intensity and competitiveness in theworld market for paper and board products. Wealso find evidence that supports the conjecturethat rich countries tend to recover relativelymore waste paper than is the case in low-incomecountries, reflecting the higher demand forwaste management and environmental policies inmore developed economies. As recovery andutilization rates are determined by economicand demographic characteristics the degree ofpolicy flexibility in affecting these rates maybe limited. In particular, an ambitiousutilization rate target may be very costly toenforce as it can conflict with existing tradepatterns of paper and board products as well aswith other environmental goals. Additionalpolicy targets may therefore be desirable,especially since paper recycling is motivatedprimarily by environmental concerns and seldomis a benign activity in itself.     

The Dilemmas of Tax Coordination in the Enlarged European Union

This study evaluates the economic effects of corporate tax coordinationin the enlarged European Union (EU) using a computable generalequilibrium model. Our main findings are as follows: (i) Corporatetax coordination can yield modest aggregate welfare gains. The2004 enlargement of the EU has increased the potential gainsfrom tax harmonization, provided corporate tax rates and taxbases are harmonized at their unweighted averages. (ii) Allscenarios for coordination leave some EU Member States as winnersand others as losers. An agreement on tax coordination is thereforelikely to require elaborate compensation mechanisms. (iii) Thelarge and diverse country effects suggest that Enhanced Cooperationfor a subset of the Member States may be the most likely routetowards tax coordination. (iv) Identifying winners and losersfrom coordination for the purpose of a compensation mechanismmay be problematic, since countries experiencing gains in GDPand welfare tend to lose tax revenues, and vice versa.

Behavioural responses to employment discrimination: a study of Hong Kong workers

This study examines the behavioural responses of Hong Kong workers to employment discrimination. Based on the exit-voice framework proposed by Hirschman, five possible responses (i.e. neglect, quit, internal voice, external voice and litigation) are identified. The effects of certain personal attributes and work-related factors on these responses are evaluated. Two different data sets, focusing on gender discrimination and family status discrimination, are analysed. The results of logistic regression indicate that workers with higher levels of education and sensitivity to discrimination are more likely to complain and less likely to neglect their work or resign. Additionally, men and women respond differently to sex-based discrimination. Work-related factors such as employment sector, job tenure and employer size are also found to exert significant effects. The theoretical and practical implications of these findings are discussed.     

Strategic behavior across gender: A comparison of female and male expert chess players

This paper aims to measure differences in risk behavior among expert chess players. The study employs a panel data set on international chess with 1.4 million games recorded over a period of 11 years. The structure of the data set allows us to use individual fixed-effect estimations to control for aspects such as innate ability as well as other characteristics of the players. Most notably, the data contains an objective measure of individual playing strength, the so-called Elo rating. In line with previous research, we find that women are more risk-averse than men. A novel finding is that men choose more aggressive strategies when playing against female opponents even though such strategies reduce their winning probability.     

Laying off credit risk: Loan sales versus credit default swaps

How do markets for debt cash flow rights, with and without accompanying control rights, affect the efficiency of lending? A bank makes a loan, learns if it needs monitoring, and then decides whether to lay off credit risk. The bank can transfer credit risk by either selling the loan or buying a credit default swap (CDS). With a CDS, the originating bank retains the loan's control rights; with loan sales, control rights pass to the loan buyer. Credit risk transfer leads to excessive monitoring of riskier credits and insufficient monitoring of safer credits. Increases in banks' cost of equity capital exacerbate these effects. For riskier credits, loan sales typically dominate CDS but not for safer credits. Once repeated lending and consequent reputation concerns are modeled, although CDSs remain dominated by loan sales for riskier credits, for safer credits they can dominate loan sales, supporting better monitoring (albeit to a limited extent) while allowing efficient risk sharing. Restrictions on the bank's ability to sell the loan expand the range in which CDSs are used and monitoring is too low.     

Crossing the Boundary of Economics and Sociology: The Case of Vilfredo Pareto

The aim of the paper is to present the economic sociology of Vilfredo Pareto. We argue that Pareto represents a mode of thinking that has not been used in economic sociology and barely considered in the other branches of sociology. We reject the habitual bifurcation of Pareto into "the economist" and "the sociologist." Pareto stresses the non-logical parts of human life, and he provides empirical examples of this in his writing. He was occupied with the dynamics in society as a result mainly of non-logical actions. We show how one may speak of a distinctly Paretian economic sociology, which primarily has its origin in his theoretical discussions. We also show that Pareto conducted empirical studies drawing from his version of economic sociology. Included is finally a presentation, as well as a discussion of Pareto's idea of rentiers and speculators, which is followed up by a more general discussion of economic types in the market.     

Service-sector competition,innovation and R&D

The central prediction of the Aghion, Bloom, Blundell and Howitt model is an inverted U-shaped relationship between innovation and competition. The model is built on the assumption of a product market and has not yet been tested on the service sector. Using detailed firm-level data on Swedish service-sector firms, we find evidence of an inverse U-shaped relationship for exporting service-sector firms. A further breakdown of innovation expenditures shows that the inverse U-shaped pattern holds for intramural R&D and training, but not for extramural R&D. Finally, the results indicate that as competition increases, small firms tend to seek strategic alliances with competitors, whereas large firms tend to reduce collaboration with competitors. The behavior of large firms can partly be due to their superior capacity to handle innovation projects internally, which will become more important if increased competition results in higher pay-offs to innovation.
