ECONOMICS OF THE LIVING DEAD*

Zombie firms are those firms that are insolvent and have little hope of recovery but avoid failure thanks to support from their banks. This paper identifies zombie firms in Japan, and compares the characteristics of zombies to other firms. Zombie firms are found to be less profitable, more indebted, more dependent on their main banks, more likely to be found in non‐manufacturing industries and more often located outside large metropolitan areas. Overall, larger size makes the firm less likely to be a zombie, but among small firms, relatively larger firms are more likely to be protected and become zombies. Controlling for profitability, the exit probability for zombie firms does not differ from that for non‐zombies. Zombie firms tend to increase employment by more (but do not reduce employment by more) than non‐zombies. Finally, when the proportion of zombie firms in an industry increases, job creation declines and job destruction increases, and the effects are stronger for non‐zombies.

Does oil corrupt? Evidence from a natural experiment in West Africa

This paper explores the oil discovery announcements in Sao Tome and Principe (1997-1999) to assess the role of natural resources in determining corruption. For this purpose, we use a natural experiment framework which contrasts Sao Tome and Principe to Cape Verde, a control West African country sharing the same colonial past and important recent economic and political shocks. Our measurement is based on tailored household surveys we conducted in both island countries. The unique survey instrument was retrospective and used personal histories to elicit memories from the respondents. We analyze changes in perceived corruption across a wide range of public services and allocations. We find clearest increases on vote buying, education (namely in the allocation of scholarships) and customs, ranging from 31 to 40% of the subjective scale. We interpret these findings as symptoms of increased competition for core state resources.

The Effect of Protest Votes on the Estimates of WTP for Use Values of Recreational Sites

Contingent valuation studies are often characterized by a considerable number of protest responses, which may cause selectivity bias on the final estimates for WTP. Sample selection models can detect and – if necessary – correct selectivity bias. In economic applications where the relevant dependent variable is continuous, sample selection models are generally estimated using Heckman's 2-step method rather than the FIML estimator. Either method has its own drawback: computational complexity for the FIML method, susceptibility to collinearity problems for the 2-step method. Using data on valuation of forest resources for recreational use, we analyse the performance of the two estimators. In this application, given the presence of some collinearity, the FIML is preferred to the 2-step method. A procedure is outlined to deal with selectivity problems in similar settings.     

Replicating Walrasian equilibria using markets for membership in labor-managed firms

In standard models of the labor-managed firm, labor is misallocated in the short run. This problem can be eliminated by introducing a market for membership in each firm. These markets substitute for the capitalist labor market and support equilibria isomorphic to Walrasian equilibria. Such LMFs resemble familiar Ward-Domar-Vanek LMFs by ensuring that firm sizes are optimal for ex post members, but they also have the property that firm sizes are optimal for workers endowed with ex ante membership rights.     

Localized innovation, localized diffusion and the environment: an analysis of reductions of CO2 emissions by passenger cars

We investigate technological change with regard to CO₂ emissions by passenger cars, using a Free Disposal Hull methodology to estimate technological frontiers. We have a sample of cars available in the UK market in the period 2000–2007. Our results show that the rates of technological change (frontier movement) and diffusion (distance to frontier at the car brand level) differ substantially between segments of the car market. We conclude that successful policies should be aimed at the diffusion of best-practice technology, and take account of the different potential for further progress between different segments of the market (e.g. diesel vs. gasoline engines and small vs. large engines).
