In this work the effects of large- and short-term debts on efficiency are tested on a set of agricultural firms. Accounting data of crop, livestock, mixed and service firms are used. First, the efficiencies of the farms are obtained by using nonparametric methods (input-oriented DEA). Then, in a...

The problem of dating the business cycle has recently received many contributions, with a lot of proposed statistical methodologies, parametric and non parametric. Despite of this, only a few countries produce an official dating of the business cycle. In this work we try to apply some procedures...

We propose a model where the growth rate volatility of a country is explained by structural change and the size of the economy. We test these predictions by means of nonparametric techniques. Growth volatility appears to (i) decrease with total GDP, (ii) increase with the share of the...

The main purpose of this paper is to evaluate small- and medium-sized display market forecasts made by a market research firm. Hypotheses concerning the relationship between stages of technology development and the accuracy of market forecasts are first developed. The hypotheses are then tested...

Despite the touted potential of e-commerce to improve agriculture profits, the literature on effectiveness of e-commerce is very limited. This paper assesses the economic impact of an electronic trade platform (i.e., MarketMaker) on agricultural producers. Contingent valuation techniques are...

This paper develops a nonparametric analysis for the sharp regression discontinuity (RD) design in which the continuous forcing variable may contain measurement error. We show that if the observable forcing variable contains measurement error, this error causes severe identification bias for the...

Electricity price time series usually exhibit some form of nonstationarity, corresponding to long-term behavior, one or more periodic components as well as dependence on calendar effects. As a result, modeling electricity prices requires accounting for both long-term and periodic components. In...

After more than two decades of transition and integration, countries in Central and Eastern Europe (CEE) still exhibit income levels that are significantly lower than the European Union (EU) average. This paper examines convergence in per-capita GDP between CEE and the EU over the period...
