With farms cultivating tens or hundreds of thousands of hectares, Ukraine is often used to demonstrate the existence of economies of scale in modern grain production. Panel data analysis for all the country's farms with more than 200 hectares in 2001-2011 suggests that higher yields and profits...

Although a large literature discusses the productivity effects of land fragmentation, measurement and potential endogeneity issues are often overlooked. This paper uses several measures of fragmentation and controls for endogeneity and crop choice by looking at inherited paddy and wheat plots to...

The coincidence of productivity improvements and growth of agriholdings in Ukraine over the last decade is often interpreted as evidence of technology-induced increasing returns to scale and superiority of very large farms. Panel data for the country's commercial farms in 2001–2012 do not...

Embarking from the concept of uniform payoff security (Monteiro P.K., Page F.H, J Econ Theory 134: 566-575, 2007), we introduce two other uniform conditions and then study the existence of mixed strategy Nash equilibria in games where the sum of the payoff functions is not necessarily upper...

Cities in transition face a unique set of challenges that came forth due to interplay of the legacy of socialist urban policies and transition to the market economy. The socialist urban policies restrained growth of the largest cities and distorted the spatial equilibrium towards more uniform...

This paper examines the importance of non-monetary dimensions of work in studies of inequality in total returns to work. Relying on the methodological advances in the field of multidimensional inequality and using the representative sample of Ukrainian industrial establishments over the period...

In this paper, we compare the charitable behavior of billionaires who inherited their wealth to the charitable behavior of those billionaires who made their own wealth. Self-made billionaires are found to be more likely to sign the ‘Giving Pledge’ and more likely to be in the Million Dollar...

This paper is aimed at widening the scope of applications of majorized correspondences. A new class of majorized correspondences -- domain U-majorized correspondences -- is introduced. For them, a maximal element existence theorem is established. Then, sufficient conditions for the existence of...

The focus of this paper is on developing geometric sufficient conditions for the existence of a mixed strategy Nash equilibrium for both diagonally transfer continuous and better-reply secure games. First, we show that employing the concept of diagonal transfer continuity in place of...

The state role in economic development policy has increased as the federal government has devolved selected programs to balance growth and incomes among different part of the country. Rapid growth in coastal states and the suburban areas around many cities, and stagnation or decline in areas...
