| This paper aims to contribute to a better understanding of possible causes of considerable production variability that characterised Russian agriculture during the last decade. The study investigates production risk and technical inefficiency as two sources that influence production variability. Using panel data from 1996 to 2001, an empirical analysis of 443 large agricultural enterprises from three regions in central, southern and Volga Russia is conducted. A production function specification accounting for the effect of inputs on both risk and technical inefficiency is found to describe production technologies of Russian farms more appropriately than the traditional stochastic frontier formulation. |

| Panel data on regional employment forecasts from structural equation econometric models and time-series models are used to examine whether accuracy of the forecasts can be predicted, both absolutely and relatively. Specification of accuracy includes the time forecast was made, forecast horizon, and regional economic/demographic characteristics. The estimated model is able to predict accuracy of each forecast set at high step lengths but is less successful at low step lengths and is not successful at all in predicting relative accuracy. Regional characteristics are significant determinants of accuracy for both sets of forecasts, but the significant characteristics differ across methodologies and step lengths. |

| This article describes a new Stata routine, xtcsd, to test for the presence of cross-sectional dependence in panels with many cross-sectional units and few time-series observations. The command executes three different testing procedures—namely, Friedman’s (Journal of the American Statistical Association 32: 675–701) (FR) test statistic, the statistic proposed by Frees (Journal of Econometrics 69: 393–414), and the cross-sectional dependence (CD) test of Pesaran (General diagnostic tests for cross-section dependence in panels [University of Cambridge, Faculty of Economics, Cambridge Working Papers in Economics, Paper No. 0435]). We illustrate the command with an empirical example. |

| Animal infectious disease outbreaks as Avian Influenza, Foot and mouth disease and Bovine Spongiform Encephalopathy can influence trade and bring economic consequences to affected countries. For this reason, this work aims to analyze the effects on meat import demand in the years of 1997 and 2003 to 2005, the Avian Influenza outbreaks period. The analytical framework used was panel data econometrics. The results point to a reduction on chicken meat demand in 1997 and increase to the other meats, indicating a possible substitution. From 2003 on, chicken meat demand showed slight increase, as did pig meat, only bovine meat demand showed a reduction. This fact can be explained by a restriction on bovine and chicken supply caused by the imposition of sanitary... |

| Farm planning often focuses on optimal diversification with respect to risk, where the risk-management strategies combine production, marketing, financial and environmental aspects of the farm-firm. In this study an empirical examination of diversification has been carried out using a sample of farms in Eastern Norway. Four measures of diversification (indices) were defined to record the risks in relation to income from farm production. Using these alternative measures of diversification and panel-data, the results show that larger farms are more diversified, and for farms in more favourable locations and access to labour, the farmers have a greater incentive to spread risk. These results suggest that diversification and farm size are positively linked and... |

| This paper examines the factors influencing farmer participation in crop insurance schemes, but unlike previous studies that focus on total demand, participation is disaggregated into entrants and those exiting. Modeling entry and exit decisions separately illustrates that the effect of a given variable is often muted by aggregation. In addition, the approach in this paper distinguishes between price and yield variables rather than total returns and is consequently able to demonstrate that price variables are particularly important for farmers considering enrolling in crop insurance, while yield variables and other risk management opportunities are more important for farmers who have been in the program but are deciding to exit. The result suggests that... |

| This paper aims at analysing the effect of democratic institutions on environmental quality (carbon dioxide per capita, sulfure dioxide per capita) and at identifying potential channel transmissions. We use panel data from 1960 to 2008 in 122 developing and developed countries and modern econometric methods. The results are as follows: Firstly, we show that democratic institutions have opposite effects on environment quality: a positive direct effect on environment quality and a negative indirect effect through investments and income inequality. Indeed, democratic institutions attract investments that hurt environment quality. Moreover, as democratic institutions reduce income inequality, they also damage environment. Secondly, we find that the direct... |

| A fixed-effects panel data demand model for five New York State markets is estimated to determine the differential impacts of generic fluid milk advertising by media type. Empirical results indicate that among the four media outlets, television advertising has the largest impact on per capita demand, followed by radio, outdoor, and print. Based on the estimated media-specific elasticities, media reallocation of advertising expenditures suggests that milk sales could increase significantly. The results indicate that cooperative media plan strategies developed between the New York regional advertising program and the national advertising programs would achieve the greatest benefits. |

| The effects of "localized depletion" of a pelagic fishery (herring) on a non-extractive marine activity (tourism) are investigated. Proponents of the localized depletion theory claim that intense fishing effort can lead to areas that are unsuitable for predators like tuna, groundfish, and whales. This leads to poor outcomes for the fishing and whale-watching industries. However, there has been no consensus in the scientific community about the existence of this phenomenon. Localized depletion would be consistent with an economic theory of joint production, in which nearshore herring stocks are an input in production of both herring and whale-watching trips. A unique dataset of daily whale-watching outcomes is combined with fishing effort and oceanographic... |
