Okres ostatnich siedmiu lat to czas istotnych zmian, jakie zaszły w gospodarce naszego kraju w wyniku wstąpienia do Unii Europejskiej. Wiele opublikowanych dotychczas raportów i analiz przedstawia różne oceny zarówno w kontekście mikro -- jak i makroekonomicznym. Wejście w życie...

From an empirical perspective, this paper critically examines the concepts of returns to scale (RTS) and economies of scale (EOS), and argues that the concept of EOS is more relevant and broader enough to exhibit proper scale economies behavior of firms. Two approaches, i.e., production function...

Standard measures of economies of scale and scope show that size does matter for German investment management companies. The average investment management company faces an increase in costs of 0.71% for a 1% increase in assets under management. Small to mid-sized companies in our example exhibit...

This paper examines the relationship between size and scale economies of cooperative banks in Japan (namely Shinkin and credit cooperatives). We use the translog cost-function methodology and intermediation approach coupled with a large set of both cross-sectional and panel data over the period...

Boussemart et al. (2009, 2010, 2018) propose to identify a global α-returns to scale that allows to minimise the inefficiency of the production set. This paper extends this notion to the concept of specific α-returns to scale. In such case, it is possible to identify the impact of each input...

This paper provides new evidence that estimates based on aggregate data will understate the true procyclicality of total factor productivity. I examine plant-level data and show that some industries experience countercyclical reallocations of output shares among firms at different points in the...

Efficiency is the main issue in any data envelopment analysis. Realizing output by a minimum of input or reaching a maximum of output by a given input is the credo, scale effects often are only a sort of accessory. In modern economics scale effects play a prominent role, however. What is the...

I develop a general framework for ex-ante analysis of a policy's effect on productivity. I use it to study the effect of carbon taxation on power plant productivity in the United States. Carbon taxes increase the price of burning fossil fuels, potentially encouraging power plants to be more fuel...

This paper proposes a unique model of capacity utilization in which the firm varies capacity utilization by a variable number of shifts when facing demand fluctuations. In the long run, the firm optimally chooses a capacity level based on expected demand conditions. In the short run, when facing...

This article proposes a non-parametric approach to measure scale and scope and a descriptive study to address the relation of the railways' production density, scale scope and efficiency using a system of equations, graphic analysis, simple regressions and a proposal for the automatic selection...
