Welfare in economics is generally conceived of in terms of the satisfaction of preferences, but a general, comparable index measure of welfare is generally not taken to be possible. In recent years, in response to the usage of measures of subjective well-being as indices of welfare in economics, a number of economists have started to develop measures of welfare based on preference-satisfaction. In order to evaluate the success of such measures, I formulate criteria of policy-relevance and theoretical success in the context of preference-satisfaction measures of welfare. I present a detailed case study of the methodological choices put forward in a prominent generalized proposal for measuring welfare through preferences recently published in the American Economic Review. I contrast this with an alternative welfare measure which also uses preferences to weight aspects of welfare: the ICECAP-A measure. I assess the methodology of both approaches in detail and argue that the two goals of a preference measure of welfare can only be satisfied at the expense of making a measure prohibitively costly.  相似文献

This article makes use of hourly crime counts to model the relationship between events that take place at the Prudential Center in Newark, NJ and robberies, an arena that has caused local controversy regarding the costs and benefits of hosting such an entertainment venue. Results from the econometric model suggest that the NHL’s New Jersey Devils ice hockey games, concerts, and Disney-themed events are all associated with increases in robbery, while various other event categories such as the NBA basketball games played by the Nets and boxing, and mixed martial arts (MMA) matches are not associated with an increase. These findings support two complementary ecological theories of crime that focus on how events provide additional opportunities for crime by increasing the associated benefits while simultaneously decreasing the cost for economically motivated offenders to take advantage of.  相似文献

Our inquiry advances a comparison of the anthropological content of Thorstein Veblen’s evolutionary perspective with the foundations of the political anthropology drawn from selected works of Pierre Clastres. We seek to establish that what can be referred to as a clastrean reference can simultaneously offer new perspectives on institutionalism, while maintaining a radical and emancipatory understanding of Veblen’s writings. In this sense, we seek to reconsider and reevaluate the role of economic surplus drawn from Veblen’s anthropology, while also offering a general and critical perspective for understanding the emergence of coercive power within societies.  相似文献

The impact of uncertainty on consumption and welfare seems obvious; because of the precautionary saving motive, higher uncertainty reduces consumption, and subsequently, deteriorates welfare. Recent several studies, however, find that this intuitive narrative is not necessarily true. This paper provides the analytical underpinnings for this. In the absence of technological progress, I find that the larger demographic shocks always reduce consumption, but improve the welfare of households. Moreover, when demographic shocks are negatively tied to technology shocks, there emerges an inverted-U relationship between the size of two shocks and consumption, and a U-shaped relationship between the size of two shocks and household welfare. These results are all characterized analytically in the framework of the stochastic two-sector growth model featuring the correlated Brownian motion process. The findings suggest that demographic policies should not be implemented with no reference to the state of technology.  相似文献

Agricultural commodity markets in developing countries often operate in a constrained environment of prohibitive transaction costs. Consequently, smallholder farmers are only partly integrated into these markets, a situation that keeps them in a lower level of development equilibrium (poverty trap). Although cooperative institutional alternatives such as Farmers’ Organizations (FOs) may reduce transaction costs and revitalize agricultural production and commercialization, they rarely have been successful in fully delivering on these promises. Against this backdrop, the World Food Programmed (WFP) has recently implemented a multi-year and multi-country pilot to increase smallholder participation in commodity markets. The projects involved investing in physical and human capacities of Farmer Organizations (FOs) to aggregate commodities and add value, as well as locally purchasing food aid from the same. The combination of interventions was expected to increase the relative price of agricultural products, particularly staple crops. In this study, using Ethiopian panel survey data, we estimated the causal income and investment effects of the Ethiopian P4P intervention among smallholders. Using an entropy balancing (EB) model and semi-parametric difference-in-difference (DID) model, we show that the P4P intervention has increased per capita consumption by smallholders. Our additional analysis confirms that this effect is heterogeneous owing to elite capture within Farmer Organizations. We also find evidence of increased food consumption scores, increased investments in child schooling, and increased asset holding among program-participating smallholders relative to comparison farmers. Policy implications are discussed.  相似文献

Do people “vote with their feet” in response to a lack of political competition? Since political competition is associated with higher growth and welfare, with the free movement of labour, we argue that it should also encourage inward migration. We test this hypothesis by using data from the US and find a strong positive relation between political competition and net migration. This result is robust to alternative specifications, alternative samples and addressing endogeneity using the Voting Rights Act to instrument for political competition. The effect is economically large, specifically, we find that an increase in political competition in the order of magnitude observed in US Southern states during the post-war period leads to an increase in net migration by between 27 and 44 individuals per 1000 population.  相似文献

This paper extends Melitz and Redding (2015) to analyze the welfare gains from trade liberalization by adding foreign direct investment(FDI). Our model predicts that with FDI activities, welfare gains from trade liberalization will be strictly lower than those in a model without FDI, but only takes exports into account. In addition, the calibrated model indicates that with FDI activities, aggregate welfare reaches its maximum when the fixed export costs are positive rather than 0. Furthermore, we decompose the welfare gains induced by trade liberalization from continuing exporters, and switchers. The results show that in any case, with or without FDI, continuing exporters contribute a larger share to welfare gains than status switching firms.  相似文献

A combined travel cost – contingent behaviour survey of residents and tourists in Catalonia is conducted on-site to examine the effects on beach recreational demand of developing an offshore wind farm (OWF) project. The survey considers four potential OWF scenarios with different degrees of visual impact. We allow for heterogeneity in trip preferences among individuals and control for on-site sampling through the use of a random parameters negative binomial (RPNB) model and a Multivariate Poisson log-normal (MPLN) model, respectively. The welfare measures derived from the RPNB model relate to the current beach users only, whereas those from the MPLN model refer to the general population of residents and tourists in Catalonia. The results show the importance of the specific place of location of the OWF project and how the installation of wind turbines would significantly decrease the demand for trips, depending on their degree of visual impacts, leading to a substantial welfare loss. However, the results also show that the project mainly would cause a displacement of trips to other beaches within Catalonia rather than outside Catalonia and that the welfare per trip measures generated by the RPNB and MPLN models substantially differ. Policy implications of these findings are discussed.  相似文献

We consider optional time-of-use (TOU) pricing for residential consumers, offered by a publicly regulated electricity supplier, as an alternative to a single TOU or flat rate structure. An equilibrium model explores and quantifies the effects of such pricing on welfare, consumption, and production costs. The supplier offers to each household a menu of possible rate structures obtained by maximizing a collective welfare function subject to three restrictions: Pareto efficiency, incentive compatibility, sufficiency of supplier revenue to cover costs. Simulations based on realistic calibration of the model demonstrate that optional pricing can increase overall consumer welfare and reduce average cost.  相似文献

Drought and high temperatures are major threats to sustainable food production and consequently the livelihoods of the majority of Africans who depend on fragile agricultural systems. As a response to these threats, climate-smart agricultural technologies, such as drought-tolerant maize (DTM) varieties, have been developed and promoted on the continent. It is well-known that the adoption of improved technologies generally impacts positively on the wellbeing of adopters. Nevertheless, the magnitude of the impact of any technology or intervention is always an empirical question. Therefore, this study sought to determine the factors that influence the adoption of DTM and subsequently estimate how yield, commercialization intensity, and farm income are affected by adoption. To establish causation, we relied on observations from 200 farm households in the Northern Region of Ghana and estimated an instrumental variable regression. Consistent with findings reported in the literature, we found that DTM adoption is primarily driven by access to seed, extension service, labor availability, and location of farm households. In addition, we found that DTM adoption positively impacts on yield and commercialization intensity. The magnitude of impact is not trivial. For example, the yield of farm households increased by more than 150% (936 kg/ha) following DTM adoption. These results imply that policy-makers and development practitioners must support research and promotion of climate-smart agriculture to improve adoption and welfare indicators, such as yield and commercialization.  相似文献
