Understanding what stimulates agribusiness firms to lobby the government and what makes the government responsive to lobbying are the two issues that have been discussed extensively in the debates concerning determinants of biotechnology policy. This paper examines the factors influencing agribusiness firms' lobbying and government response using econometric modeling on a new data set of 160 leading agribusiness firms in the food, feed, chemical, and seed industries in China. The results show that approximately 10% of agribusiness firms lobbied the government about biotechnology policy and regulations and over half of those that lobbied received a verbal or written acknowledgment from government agencies. Seed and feed companies are more likely to engage in lobbying than chemical companies. Owning GM patents not only has a positive impact on firms' lobbying activities, but firms with these patents are more likely to receive a government response to their lobbying efforts. The experience of selling GM products does not significantly influence lobbying activities or response from the government.  相似文献

Against a backdrop of increased levels of marketization of welfare services in OECD countries, this article aims to shed light on the separate effects of private ownership and competition for the market on service quality. Using residential elder care homes in Sweden as our case, we leverage unique panel data of ownership and competition against a set of indicators, pertaining to the structure, process, and outcome dimensions of care quality. The main finding of our analyses is that competition for the market does surprisingly little for quality: private entrepreneurs perform neither better nor worse under stiff competition and the quality of care is approximately the same in those nursing homes that are exposed to the market as in those that are not.  相似文献

Theories from psychology suggest that voters’ perceptions of political positions depend on their non-policy related attitudes towards the candidates. A voter who likes (dislikes) a candidate will perceive the candidate’s position as closer to (further from) his own than it really is. This is called projection. If voters’ perceptions are not counterfactual and voting is based on perceived policy positions then projection gives generally liked candidates an incentive to be ambiguous. In this paper we extend the standard Downsian model in order to investigate under what conditions this incentive survives in the strategic setting of electoral competition.  相似文献

Two distinct literatures have studied the macroeconomic effects of electoral systems and of labor market structures, respectively. Results include a positive association between proportional representation (PR) electoral systems and growth, but also between PR and inflation, as well as negative or hump‐shaped relationships between labor market coordination and the ‘misery variables’, unemployment and inflation. However, these results could be biased; particular electoral system and labor market features co‐vary systematically, and extant studies have typically not taken this into account. Effects attributed to PR systems could really stem from labor market coordination, and vice versa. In this article the relationships with macroeconomic outcomes for both electoral systems and labor market structures are re‐evaluated by modelling them jointly. Employing data from more than 30 democracies, with time‐series from the period 1960–2010, some robust and some non‐robust associations are identified. First, PR systems are, indeed, associated with higher growth rates, but not with higher inflation. Regarding labor market coordination, robust curvilinear relationships with unemployment and inflation are identified; intermediate levels of coordination correspond with worse macroeconomic performance – albeit not lower growth – even when accounting for electoral system features.  相似文献
