We study a constitutional change in the German State of Bavaria where citizens, not politicians, granted themselves more say in politics at the local level through a state initiative election in 1995. This institutional setting allows us to observe revealed preferences for direct democracy and to identify factors which explain these preferences. Empirical evidence suggests that support for direct democracy is related to dissatisfaction with representative democracy in general rather than with an elected governing party. 相似文献

The colonial legacy of African underdevelopment is widely debated but hard to document. In this article, occupational statistics from Protestant marriage registers of historical Kampala are used to investigate the hypothesis that African gender inequality and female disempowerment are rooted in colonial times. We find that the arrival of Europeans in Uganda ignited a century‐long transformation of Kampala involving a gender Kuznets curve. Men rapidly acquired literacy and quickly found their way into white‐collar (high‐status) employment in the wage economy built by the Europeans. Women took somewhat longer to obtain literacy and considerably longer to enter into white‐collar and waged work. This led to increased gender inequality during the first half of the colonial period. However, gender inequality gradually declined during the latter half of the colonial era, and after Uganda's independence in 1962 its level was not significantly different from that of pre‐colonial times. The data presented here also support Boserup's view that gender inequality was rooted in indigenous social norms: daughters of African men who worked in the traditional, informal economy were less well‐educated, less frequently employed in formal work, and more often subjected to marital gender inequality than daughters of men employed in the modernized, formal economy created by the Europeans. 相似文献

This paper studies an incomplete information model in which a preventable accident occurred. The judge determining punitive damages observes the firm's (defendant) investment decisions, but is uninformed about the firm's experience adopting safety measures. Our model allows firms to file an appeal if the judge's verdict is incorrect, which the judge may accept or reject. We identify under which conditions a separating equilibrium exists where the firm's investment decisions signal its type to the judge, who responds with a correct verdict, thus avoiding future appeals. Our paper also finds conditions under which a pooling equilibrium exists whereby the firm's investment in precaution conceals its type from the judge, who can respond with an incorrect verdict thus giving rise to appeals. Furthermore, we show that the separating equilibrium is more likely to arise if the percentage of revenue that defendants are required to pay in punitive damages decreases, if the punitive‐to‐compensatory ratio increases, and if the legal cost of filing an appeal increases. 相似文献

This study assesses changes over the past decade in the farm size distributions of Ghana, Kenya, Tanzania, and Zambia, drawing on two or more waves of nationally representative population‐based and/or area‐based surveys. Analysis indicates that much of Sub‐Saharan Africa is experiencing major changes in farm land ownership patterns. Among all farms below 100 hectares in size, the share of land on small‐scale holdings under five hectares has declined except in Kenya. Medium‐scale farms (defined here as farm holdings between 5 and 100 hectares) account for a rising share of total farmland, especially in the 10–100 hectare range where the number of these farms is growing especially rapidly. Medium‐scale farms control roughly 20% of total farmland in Kenya, 32% in Ghana, 39% in Tanzania, and over 50% in Zambia. The numbers of such farms are also growing very rapidly, except in Kenya. We also conducted detailed life history surveys of medium‐scale farmers in each of these four countries and found that the rapid rise of medium‐scale holdings in most cases reflects increased interest in land by urban‐based professionals or influential rural people. About half of these farmers obtained their land later in life, financed by nonfarm income. The rise of medium‐scale farms is affecting the region in diverse ways that are difficult to generalize. Many such farms are a source of dynamism, technical change, and commercialization of African agriculture. However, medium‐scale land acquisitions may exacerbate land scarcity in rural areas and constrain the rate of growth in the number of small‐scale farm holdings. Medium‐scale farmers tend to dominate farm lobby groups and influence agricultural policies and public expenditures to agriculture in their favor. Nationally representative Demographic and Health Survey (DHS) data from six countries (Ghana, Kenya, Malawi, Rwanda, Tanzania, and Zambia) show that urban households own 5–35% of total agricultural land and that this share is rising in all countries where DHS surveys were repeated. This suggests a new and hitherto unrecognized channel by which medium‐scale farmers may be altering the strength and location of agricultural growth and employment multipliers between rural and urban areas. Given current trends, medium‐scale farms are likely to soon become the dominant scale of farming in many African countries. 相似文献

This paper develops a method to compute the equilibrium correspondence for exchange economies with semi-algebraic preferences. Given a class of semi-algebraic exchange economies parameterized by individual endowments and possibly other exogenous variables such as preference parameters or asset payoffs, there exists a semi-algebraic correspondence that maps parameters to positive numbers such that for generic parameters each competitive equilibrium can be associated with an element of the correspondence and each endogenous variable (i.e. prices and consumptions) is a rational function of that value of the correspondence and the parameters.This correspondence can be characterized as zeros of a univariate polynomial equation that satisfy additional polynomial inequalities. This polynomial as well as the rational functions that determine equilibrium can be computed using versions of Buchberger's algorithm which is part of most computer algebra systems. The computation is exact whenever the input data (i.e. preference parameters etc.) are rational. Therefore, the result provides theoretical foundations for a systematic analysis of multiplicity in applied general equilibrium. 相似文献

In this paper, we examine non-parametric restrictions on counterfactual analysis in a dynamic stochastic general equilibrium model. Under the assumption of time-separable expected utility and complete markets all equilibria in this model are stationary. The Arrow-Debreu prices uniquely reveal the probabilities and discount factor. The equilibrium correspondence, defined as the map from endowments to stationary (probability-free) state prices, is identical to the equilibrium correspondence in a standard Arrow-Debreu exchange economy with additively separable utility. We examine possible restriction on this correspondence and give necessary as well as sufficient conditions on profiles of individual endowments that ensure that associated equilibrium prices cannot be arbitrary. Although restrictions on possible price changes often exist, we show that results from a representative-agent economy usually do not carry over to a setting with heterogeneous agents. 相似文献

Although equilibrium allocations in models with incomplete markets are generally not Pareto-efficient, it is often argued that quantitative welfare losses from missing assets are small when time horizons are long and shocks are transitory. In this paper we use a computational analysis to show that even in the simplest infinite horizon model without aggregate uncertainty welfare losses can be substantial. Furthermore we show that in this model welfare losses from incomplete markets do not necessarily disappear when one considers calibrations of the model in which agents become very patient. We argue that when the economic model is calibrated to higher frequency data, the period persistence of negative income shocks must increase as well. In this case the welfare loss of incomplete markets remains constant even as agents' rate of time preference tends to one. Journal of Economic Literature Classification Numbers: D52, D58, D60. 相似文献

In the past, Energy Utility Companies (EUC) in Germany bought their electricity demand with a strategy that used planned sales volumes as control factor for procurement. However, this approach has the disadvantage that the open position defined as the difference between electricity sold to the customer and electricity bought at the wholesale market is not monitored. Thus, the price risk is measured incorrectly. To avoid these unnecessary risks, we propose that optimal portfolio management in liberalised energy markets should constantly monitor electricity sales volumes and electricity bought. This approach has the advantage that the open position and thus the price risk can be computed continuously and can thus be managed and monitored. However, higher data requirements have to be fulfilled when this strategy is applied. Nonetheless, the process is manageable with modern IT-systems. The main ideas in this paper can be transferred to the gas market. 相似文献

This article proposes that construal level moderates consumer evaluation of different appeals (emotional vs. cognitive appeals) in advertisements. Low-level construal is associated with close psychological distance; this condition implies that people with low-level construal can feel an emotion more intensely than those with high-level construal. Consequently, consumers with low-level construal could positively relate with the emotional appeal ad, and they would evaluate an ad with emotional appeal more favorably than an ad with cognitive appeal. However, this effect does not occur among consumers who construe information at high-level, due to the fact that they are able to focus on the central and positive features of different appeals. 相似文献
