We develop a theoretical model in which firms are either private or state-owned. When firms become insolvent, the government can intervene with general measures, like subsidies, or by nationalizing firms. The government only intervenes when the bankruptcy of a firm entails social costs. In a stylized model, we analyze how government interventions affect allocative and productive efficiency. Nat...

We estimate a model of ticket resale that incorporates strategic effort choices by consumers and brokers in the primary market, rational anticipation of resale activity, and the resulting resale market equilibrium. Estimation is based on a unique dataset that combines detailed sales data from both the primary and secondary markets for a sample of major rock concerts. We use the estimated model ...

Abstract The United Nations’ Sustainable Development Goals envisage halving food waste by 2030. A goal to which the German Tafel banks can make a significant contribution also optimising distribution of donations. We analyse potential cost-neutral exchange surplus donations between points Berliner Tafel, based on real-time data. This helps, one hand, ensure that consumption needs clients are co...

In some situations the producers desire to maximize total profit of Decision Making Units (DMUs) while the inputs and outputs prices of DMUs change from one time period to another. In this paper, the researchers develop productivity index when producers are going to maximize total profit when the price of inputs and outputs are known.The proposed method uses all price information about inputs a...

This paper discusses and reviews the use of super-eciency approach in data envelopment analysis (DEA) sensitivity analyses. It is shown that super-eciency score can be decomposed into two data perturbation components of a particular test frontier decision making unit (DMU) and the remaining DMUs. As a result, DEA sensitivity analysis can be done in (1) a general situation where data for a tes...

Three dimensions of the performance of firms in Ghana’s manufacturing sector are investigated in this paper: their technology and the importance of technical and allocative efficiency. We show that the diversity of factor choices in not due to a non-homothetic technology. Observable skills are not quantitatively important as determinants of productivity. Technical inefficiency is not lower in f...
