On the dynamics of inequality 总被引:1,自引:0,他引:1
Debraj Ray 《Economic Theory》2006,29(2):291-306
The dynamics of inequality are studied in a model of human capital accumulation with credit constraints. This model admits a multiplicity of steady state skill ratios that exhibit varying degrees of inequality across households. The main result studies equilibrium paths. It is shown that an equilibrium sequence of skill ratios must converge monotonically to the smallest steady state that exceeds the initial ratio for that sequence. Convergence is “gradual" in that the steady state is not achieved in finite time. On the other hand, if the initial skill ratio exceeds the largest steady state, convergence to a steady state is immediate.This paper is based on unpublished notes from 1990; see http://www.econ.nyu.edu/user/debraj/DevEcon/Notes/incdist.pdf. Two considerations suggest that these results may be worth reporting in print. First, the existence of a sizeable recent literature indicates that these relatively early notes may have value outside a filing cabinet or a private webpage. Second, Mukul Majumdar’s own research on economic growth with a nonconvex technology is an even earlier precursor to some of this literature, so the current outlet – a special issue in his honor – seems appropriate. Conversations with Glenn Loury simplified the proof of the main result. I thank Dilip Mookherjee for many useful discussions, and two anonymous referees for helpful comments on an earlier draft. Funding from the National Science Foundation under grant number 0241070 is acknowledged. This paper is dedicated with much affection and warm admiration to Mukul Majumdar – or to Mukulda, as I always think of him – on the occasion of his 60th birthday. 相似文献

This paper argues that the slow U.S. recovery after the 2008–2009 recession was due to sluggish government spending. The analysis uses a structural macroeconometric model. Conditional on government policy, the errors in predicting output for the 2009.4–2017.4 period are within what one would expect historically. Productivity and labor force participation are endogenous variables in the model, and so their behaviors in this period are a consequence of the slow growth rather than a cause. 相似文献

Analyses of a large retail scanner price data set reveal a new and surprising regularity - small price increases occur more frequently than small price decreases for price changes of up to 10¢. That is, we find asymmetric price adjustment “in the small.” Furthermore, it turns out that inflation offers only a partial explanation for the finding. Indeed, substantial proportion of the asymmetry remains unexplained, even after accounting for the inflation. For example, the asymmetry holds also after excluding periods of inflation from the data, and even for products whose price had not increased. The findings hold for different aggregate and disaggregate measures of inflation and also after allowing for lagged price adjustments. 相似文献

This paper investigates whether the provision of non-audit services (NAS) to audit clients impairs auditor independence of mind and independence in appearance. The main contributions of this paper are in terms of its timeliness with respect to regulatory changes, the simultaneous examination of both forms of auditor independence and the methodological innovation whereby it uses a variable derived from the level of abnormal audit fees as a moderating variable in order to capture the direct impact of the NAS fee level on auditor independence as well as how its influence is moderated by the level of unexpected audit fees. Our results indicate that auditor independence of mind is compromised by the size of NAS fees, particularly for clients who pay below the level of expected audit fee. The stock market perceives that auditor independence is compromised by NAS fees but, at the same time, additional tests indicate that there are benefits that accrue from NAS and, in particular, the relation between return and non-discretionary net income is increasing in NAS fees. The balance of evidence suggests that the European Union is correct in undertaking some reform of the auditing market. 相似文献

Evaluation of value of irrigation water is essential for supporting policy decision making relating to investments in the irrigation sector, efficient allocation of irrigation water and water pricing and for crafting policies to compare the variable impacts of water reform within and across sectors of the economy. This paper asks the question of how much an established irrigator would pay for water and at what price farmers planning to expand the area they have under irrigation would consider paying for the right to access water. An analytical framework is developed to estimate the net present value of both annual and perennial agricultural activities in the Murrumbidgee catchment. Using these estimates the total value of water used in Murrumbidgee catchment is estimated. An aggregate water supply curve is derived for the catchment from where water may be acquired from irrigators for environmental flows. 相似文献

Testing the CAPM revisited 总被引:1,自引:0,他引:1
This paper re-examines the tests of the Sharpe–Lintner Capital Asset Pricing Model (CAPM). The null that the CAPM intercepts are zero is tested for ten size-based stock portfolios and for twenty five book-to-market sorted portfolios using five-year, ten-year and longer sub-periods during 1965–2004. The paper shows that the evidence for rejecting the CAPM on statistical grounds is weaker than the consensus view suggests, and highlights the pitfalls of testing multiple hypotheses with the conventional heteroskedasticity and autocorrelation robust (HAR) test with asymptotic P-values. The conventional test rejects the null for almost all sub-periods, which is consistent with the evidence in the literature. By contrast, the null is not rejected for most of the sub-periods by the new HAR tests developed by Kiefer et al. (2000), Kiefer and Vogelsang (2005), and Sun et al. (2008). 相似文献

The face of unionism in the United States is becoming increasingly public sector. On the surface, public sector unionism appears
as a bright spot for labor. A more careful examination of the data, however, reveals that such unionism is at a standstill.
Absolute growth has been insufficient to offset losses in private industry, and it is largely tied to increases in public
employment. Public employee unions face numerous serious challenges, and questions have been raised in the federal service
about the very legitimacy of union representation. Future scenarios suggest that public sector unionism as a whole will likely
remain in a more or less stagnant position. 相似文献

Mitigating response distortion in answers to sensitive questions is an important issue for business ethics researchers. Sensitive questions may be asked in surveys related to business ethics, and respondents may intend to avoid exposing sensitive aspects of their character by answering such questions dishonestly, resulting in response distortion. Previous studies have provided evidence that a surveying procedure called the randomized response technique (RRT) is useful for mitigating such distortion. However, previous studies have mainly applied the RRT to individual dichotomous questions (e.g., yes/no questions) in face-to-face survey settings. In this study, we focus on behavioral research examining the relationships between latent variables, which are unobserved variables measured by multiple items on Likert or bipolar scales. To demonstrate how the RRT can be applied to obtain valid answers from respondents answering a self-administered online questionnaire with Likert and bipolar scales, we build a behavioral model to study the effect of punishment severity on employees’ attitudes toward misuse of information systems resources in the workplace, which in turn influence misuse behavior. The survey findings meet our expectations. The respondents are generally more willing to disclose sensitive data about their attitudes and actual behavior related to misuse when the RRT is implemented. The RRT’s implications for causal modeling and the advantages and challenges of its use in online environments are also discussed. 相似文献

This paper examines whether there exist productivity spillovers from foreign direct investment (FDI) to domestic firms at the regional level, using firm-level panel dataset covering 22 manufacturing industries in India from 2000 to 2012. In order to estimate the productivity spillovers from FDI at the regional level, we select 10 industrial clusters across 4 regions in India. In estimating productivity, we control for a possible simultaneity bias by using semi-parametric estimation techniques. We find that local firms benefit from horizontal and vertical FDI, but the benefits from the latter are found to be substantially stronger. The absorptive capacity of domestic firms is highly relevant to harvest the spilled technology from foreign-owned firms. Furthermore, we find that domestic firms belonging to high-technology industries benefit more from FDI at the regional level. We also find that market concentration is a crucial conduit for firm innovation, technological upgradation, and having a direct effect on local firm total factor productivity. 相似文献

In a two-sector, general-equilibrium model with labor-market search frictions, we find that the wage increases and sectoral unemployment decreases upon offshoring in the presence of perfect intersectoral labor mobility. If, as a result, labor moves to the sector with the lower (or equal) vacancy costs, there is an unambiguous decrease in economywide unemployment. With imperfect intersectoral labor mobility, unemployment in the offshoring sector can rise, with an unambiguous unemployment reduction in the non-offshoring sector. Imperfect labor mobility can result in a mixed equilibrium in which only some firms offshore, with unemployment in the offshoring sector rising. 相似文献
