In the standard framework of data envelopment analysis (DEA) models, the returns to scale are fully characterized using the multiplier on the convexity constraint of inefficient decision making units (DMU) using the projection of the input-output vector on the frontier. In this note, we investigate how the returns to scale measurements in DEA models are affected by the presence of regulatory co...

We analyse the impact of ICT spillovers on productivity using company data for the U.S. We account for interand intra-industry spillovers and assess the role played by firm’s absorptive capacity. Our results show that intra-industry ICT spillovers have a contemporaneous negative effect that turns positive 5 years after the initial investment. For inter-industry spillovers both contemporaneous a...

We document the evolution of productivity in a steel mini mill with fixed capital, producing an unchanged product with Leontief technology working 24/7. Despite—almost—unchanged production conditions, output doubled within the sample period (12 years). We decompose the gains into downtime reductions, more rounds of production per time, and more output per run. After attributing productivity gai...

For a stable supply of electricity power plants are required to provide ancillary services in addition to energy production. This paper suggests a solution for optimal bidding strategy for hydroelectric units operating in markets where both energy and ancillary services are priced simultaneously. The model is illustrated on a numerical example of a hydro unit operating in such markets of New Yo...

In this paper we present new measures for the bias in an import price index due to outsourcing. The m easure is developed fi rst for a high ly simplif ied case for the purpose of conveying the rationale for the measure. It is then generalized, yielding a m eaasure that could b e used in empirical stu dies. Before taking up this bias measurement problem , however, we expl ain the m easurement co...

We experimentally test the effect of sunk costs on decision making. In the experiment, subjects play the role of price–setting duopolists. Both firms have identical costs, including an exogenous sunk cost that varies across sessions over six different values. We observe that the sunk cost has a U–shaped effect: from low to medium levels, average prices decrease, but from medium to high levels, ...

This study presents the results of an extensive Monte Carlo experiment to compare di erent methods of e ciency analysis. In addition to traditional parametric-stochastic and nonparametric-deterministic methods recently developed robust nonparametric-stochastic methods are considered. The experimental design comprises a wide variety of situations with di erent returns-to-scale regimes, substitut...

This study examines the effect of labour market regulations on Greek tourism industry performance. The industry, steam engine economy, always drives to enhance efforts reach further savings in operating costs. However, that influence sector’s ability adjust costs have not been thoroughly investigated. We present a novel methodology permits evaluation technical and allocative efficiency one step...

We develop a methodology to analyze capital misallocation (dispersion in static marginal products) measure the contributions of technological/informational frictions and a rich class of firm-specific factors. An application to Chinese manufacturing firms reveals that adjustment costs and uncertainty, while significant, generate only a modest amount of MPK dispersion, which stems largely from ot...
