The Mirrleesian model of income taxation restricts attention to simple allocation mechanism with no strategic interdependence, i.e., the optimal labor supply of any one individual does not depend on the labor supply of others. It has been argued by Piketty (2009) [12] that this restriction is substantial because more sophisticated mechanisms can reach first-best allocations that are out of reach with simple mechanisms. In this paper, we assess the validity of Piketty?s critique in an independent private values model. As a main result, we show that the optimal sophisticated mechanism is a simple mechanism, or, equivalently, a Mirrleesian income tax system. 相似文献

This paper studies the determinants of technological catch‐up considering spatial and sectoral aggregation of industries. We investigate how geographical and technological proximity to the technology leader impact regional employment growth. We model technological progress by means of a hierarchical process of catch‐up to the technology leader. We also incorporate measures for knowledge spillover effects to test the roles of competition, specialisation, and diversity at the industry level. Empirical results using data at the county level for different economic sectors (2‐dig NAICS) for the United States indicate that human capital plays a crucial role in promoting sectoral employment growth. The association between technological/geographical distance to the technology leader and employment growth varies across sectors. 相似文献

We highlight the problem of loneliness, and argue that it is not only a public health issue but also an economic problem. We provide a brief review of findings from the key literature on the associations between loneliness, mental and physical health, and healthcare costs; and then present some evidence on its trends, the extent of socioeconomic inequalities and its links with health and healthcare usage, in Australia. We hope to encourage further economics research on loneliness, and related issues of social isolation and poor social support, to aid the design of policies and interventions to reduce loneliness. 相似文献

Summary. We provide two new, simple proofs of Afriats celebrated theorem stating that a finite set of price-quantity observations is consistent with utility maximization if, and only if, the observations satisfy a variation of the Strong Axiom of Revealed Preference known as the Generalized Axiom of Revealed PreferenceReceived: 12 June 2003, Revised: 9 October 2003, JEL Classification Numbers:

This study examines whether nonhomothetic preferences underlie the “missing trade” problem associated with factor content of trade models. We first find that per capita income goes a long way in explaining differences in goods consumption across countries. We then find a striking correlation between the factor content of consumption and per capita income, and show that accounting for this is a key part of resolving the case of the missing trade. However, nonhomothetic preferences over broad categories of expenditure play only a small role in this phenomenon. Rather, we find that as income grows, spending is directed towards the relatively capital‐intensive version of a given good. Since recent research shows that capital intensity is correlated with quality ( Schott, 2004 ), our results suggest that within‐product quality differences are likely important for explaining the factor content of trade, whereas nonhomothetic preferences over broad categories of expenditure are much less so. 相似文献

Climate policy planners and the public should be aware of both economic challenges and arguments that may influence the intensity of the climate policies with which they have to cope. This article examines six economic challenges: cap‐and‐trade versus taxes, non‐price regulations, energy efficiency policies, mitigation versus adaptation, trade effects, and transmission planning. Three additional challenges affect the end itself: ‘fat tails’, discount rates, and whether environmental protection should be evaluated by willingness to pay. If future generations cannot compensate the present for climate policy costs, climate policy is inherently redistributive and cannot be evaluated through cost–benefit analysis alone. 相似文献

This paper is an updated study on the causes of economic insecurity in the United States. The authors have constructed an aggregate composite index that measures objectively the major causes of economic insecurity (CEI) in the United States. The CEI index consists of 11 variables that can cause economic insecurity. The time period under investigation is 1960 through 2001. A rising CEI index indicates that the causes of economic insecurity in the United States have increased in relative importance, which results in an increase in economic insecurity. Conversely, a falling CEI index indicates that the causes of economic insecurity have declined in relative importance, which results in a reduction of economic insecurity. However, despite substantial economic growth in the American economy from 1960 through 2001, the CEI index overall showed little improvement. The major conclusion is that the CEI index was 9 percent higher in 2001 than it was in 1960. This result was due largely to the increase in divorce, violent crime, rising out-of-pocket expenditures for health care, inflation, and unemployment. The results for subperiods are dramatically different, and we think more interesting, than the overall results. During the 1960s, there was a small decline in the CEI index. The 1970s showed a dramatic increase in the CEI index, which reflected both high unemployment rates and inflation rates during this period. The 1980s experienced fluctuating levels in the index but little overall change, and the 1990s experienced a sharp decline in the CEI index due largely to a robust economy. The CEI index has increased more recently, which reflects largely the recent 2001 business recession. The correlation coefficient of the CEI index with the University of Michigan's well-known Index of Consumer Sentiment is ?676. This figure shows that as the CEI index rises, consumer sentiment about the American economy becomes pessimistic and negative. 相似文献

This study estimates the demand system using Japanese micro data and calculates the cost of living index (COLI) to assess the substitution bias in the Consumer Price Index. The estimated bias during the sample period of 1982–2000 is about 0.06 percentage points, which is larger than the estimates calculated from a superlative index. The difference between the COLI and a superlative index can be explained with the upward movements of the average utility level in Japan, since the cost of living for the rich has grown more rapidly than that for the poor. 相似文献
