INTRODUCTION From the point of view of workplace safety, it is important to know whether having a temporary job has an effect on the severity of workplace accidents. We present an empirical analysis on the severity of workplace accidents by type of contract. METHOD We used microdata collected by the Italian national institute managing the mandatory insurance against work related accidents. We...

We introduce SyVOLT, a plugin for the Eclipse development environment for the verification of structural pre/post-condition contracts on model transformations. The plugin allows the user to build transformations in our transformation language DSLTrans using a visual editor. The pre-/post-condition contracts to be proved on the transformation can also be built in a similar interface. Our contrac...

A large literature in empirical public finance relies on "bunching" to identify a behavioral response to non-linear incentives and to translate this response into an economic object to be used counterfactually. We conduct this type of analysis in the context of prescription drug insurance for the elderly in Medicare Part D, where a kink in the individual's budget set generates substantial bunch...

This introductory chapter to Economic Models of Law (forthcoming, Edward Elgar) discusses the use of economic models for understanding law. It also provides a survey of the contents of the volume, which consist of twenty-one previously published articles in the areas of torts, contracts, property, and legal process.

The coordination of two-echelons supply chain by buyback contract under the imperfect product quality and fuzzy demand environment is investigated in this paper. The mathematical models are built based on credibility theory, and the optimal parameters of buyback contract are obtained. In addition, the influence of the imperfect product rate on the parameters of buyback contract is analyzed. Fin...

In this paper, we consider the revenue sharing contract between supply chain actors in a multi-echelon supply chain, where the demand of the customers and retail price are fuzzy variables. The centralized decision making system and a coordinating contract, namely, the revenue sharing contract with fuzzy demand and asymmetric information are proposed. To derive the optimal solutions, the fuzzy s...
