Coordination in Public Good Provision: How Individual Volunteering is Impacted by the Volunteering of Others

In this analysis, we examine the relationship between an individual's decision to volunteer and the average level of volunteering in the community where the individual resides. Our theoretical model is based on a coordination game , in which volunteering by others is informative regarding the benefit from volunteering. We demonstrate that the interaction between this information and one's private information makes it more likely that he or she will volunteer, given a higher level of contributions by his or her peers. We complement this theoretical work with an empirical analysis using Census 2000 Summary File 3 and Current Population Survey (CPS) 2004-2007 September supplement file data. We control for various individual and community characteristics, and employ robustness checks to verify the results of the baseline analysis. We additionally use an innovative instrumental variables strategy to account for reflection bias and endogeneity caused by selective sorting by individuals into neighborhoods, which allows us to argue for a causal interpretation. The empirical results in the baseline, as well as all robustness analyses, verify the main result of our theoretical model, and we employ a more general structure to further strengthen our results.

Public Sector Pay in Finland

This study analyses the forces determining public and private sector pay in Finland. The data used is a 7 per cent sample taken from the Finnish 2001 census. It contains information on 42 680 male workers, of which 8 759 are employed in public and 33 921 in the private sector. The study documents and describes data by education, occupation and industry. We estimate earnings equations for the whole sample as well as for four industries (construction, real estate, transportation and health) that provide an adequate mix of both public and sector workers. The results suggest that the private-public sector pay gap of about one per cent can be accounted for by differences in observable characteristics between the sectors (3.4 per cent) and lower returns from these characteristics (-2.3 per cent). However, the industry-level analysis indicates that the earnings gaps vary across industries, and are negative in some cases. These inter-industry differences in public-private gaps persist even when the usual controls are introduced. This suggests that public sector wage setters need greater local flexibility, which should result in less uniform wages within the public sector.

On Public Inefficiencies in a Mixed Duopoly

The aim of this paper is to investigate the welfare effect of a change in the public firms objective function in oligopoly when the government takes into account the distortionary effect of rising funds by taxation (shadow cost of public funds). We analyze the impact of a shift from welfare- to profit-maximizing behaviour of the public firm on the timing of competition by endogenizing the determination of simultaneous (Nash-Cournot) versus sequential (Stackelberg) games using the game with observable delay proposed by Hamilton and Slutsky (1990). Differently from previous work that assumed the timing of competition, we show that, absent efficiency gains, instructing the public firm to play as a private one never increases welfare. Moreover, even when large efficiency gains result from the shift in public firm's objective, an inefficient public firm that maximizes welfare may be preferred.
