| Proponents of environmental policies based on liability assert that strict liability imposed on the polluter will induce firms to handle hazardous wastes properly and to avoid disposing them into the environment. Economic theory and a few well-publicized cases, however, suggest that a number of factors may dilute the incentives posed by strict liability. In this paper, we run regressions relating unintended releases of pollution into the environment (aggregated at the state level, and followed over nine years from 1987 to 1995) to the imposition of strict liability on the polluter, exploiting variation across states in the liability provisions of their mini-Superfund laws, and in the years these were adopted. We experiment with instrumental variable... |

| Theoretical models suggest that decisions about diet, weight and health status are endogenous within a utility maximisation framework. In this paper, we model these behavioural relationships in a fixed-effect panel setting using a simultaneous equation system, with a view to determining whether economic variables can explain the trends in calorie consumption, obesity and health in OECD countries and the large differences among countries. The empirical model shows that progress in medical treatment and health expenditure mitigates mortality from diet-related diseases, despite rising obesity rates. While the model accounts for endogeneity and serial correlation, results are affected by data limitations. |

| This paper investigates how the ownership and the procedure for the selection of firms operating in the local public transport sector affect their productivity. In order to compare different institutional regimes, we carry out a comparative analysis of 72 companies operating in large European cities. This allows us to consider firms selected either through competitive tendering or negotiated procedures. The analysis of the data on 77 European firms over the period 1997-2006 indicates that firms operate under constant returns to scale. Retrieving the residuals we obtain a measure of total factor productivity, which we regress on firm and city characteristics. We find that when firms are totally or partially in public hands their productivity is lower.... |

| In this paper we investigate Dutch corporate liquidity management in general, and target adjustment behaviour in particular. To this purpose, we use a simple error correction model of corporate liquidity holdings applied to firm-level data for the period 1977-1997. We confirm the existence of long-run liquidity targets at the firm level. We also find that changes in liquidity holdings are driven by short-run shocks as well as the urge to converge towards targeted liquidity levels. The rate of target convergence is higher when we include more firm-specific information in the target. This result supports the idea that increased precision in defining liquidity targets associates with a faster observed rate of target convergence. It also suggests that the slow... |

| Estimating the panel gravity model with bilateral pair and country-by-time fixed-effects separately for each seafood product, we found that food safety regulations have differential effects across seafood products. In all three industrialized markets, shrimp is most sensitive, while fish is the least sensitive to changing food safety policies. The enforcement of the US HACCP, the EU Minimum Required Performance Level and the Japanese Food Safety Basic Law caused a loss of 90.45%, 99.47%, and 99.97% to shrimp trade in these markets, and a reduction associated with fish trade was 66.71%, 82.83%, and 89.32%. |

| The possibility that workers could be adversely affected by environmental policies imposed on heavily regulated industries has led to claims of a "jobs versus the environment" trade-off by both business and labor leaders. The present research examines this claim at the industry level for four heavily polluting industries: pulp and paper mills, plastic manufacturers, petroleum refiners, and iron and steel mills. By focusing on labor effects across an entire industry, we construct a measure relevant to the concerns of key stakeholders, such as labor unions and trade groups. We decompose the link between environmental regulation and employment into three distinct components: factor shifts to more or less labor intensity, changes in total expenditures, and... |

| This paper provides a comparative analysis of statistical methods to evaluate the consumer perception about the quality of Services of General Interest. The evaluation of the service quality perceived by users is usually based on Customer Satisfaction Survey data and an ex-post evaluation is then performed. Another approach, consisting in evaluating Consumers preferences, supplies an ex-ante information on Service Quality. Here, the ex-post approach is considered, two non-standard techniques - the Rasch Model and the Nonlinear Principal Component Analysis - are presented and the potential of both methods is discussed. These methods are applied on the Eurobarometer Survey data to assess the consumer satisfaction among European countries and in different... |

| This article examines the effects of the application of panel data estimation methods on a system of equations with unbalanced panel data. We apply pooled, random-effects, and fixed-effects estimation in three data sets: small, medium, and large farms to examine the relationship between farm size and the elasticity of cotton supply with respect to cotton price. Our results indicate that the adoption of various estimation methods entails different estimated parameters both in terms of their absolute value and in terms of their statistical significance. Additionally, the elasticity of cotton supply with respect to price varies according to farm size. |

| Comparisons between the return to wine and standard financial assets are complicated in that the return to wine must be estimated from infrequent sales of heterogeneous wine brands. Wine returns can be estimated using several different approaches, and here the performance of the hedonic approach, repeat sales approach, and hybrid approach are compared using 14,102 auction sale observations for Australian wine over the period 1988 to 2000. For the data set considered the results show that the hybrid approach provides the most efficient estimates, and that the repeat sales approach provides significantly higher total return estimates than the other two approaches. The portfolio diversification benefit attributed to holding wine is then shown to vary with... |
