In this paper we estimate the DEA technical efficiency for 4796 Brazilian municipalities, by applying a recently proposed
“Jackstrap” method, which combines Bootstrap and Jackknife resampling techniques, to reduce the effect of outliers and possible
errors in the data set. We perform calculations to identify and eliminate high leverage municipalities, using different variants
of Data Envelopment Analysis (DEA), as well as Free Disposal Hull (FDH). Corroborating previous results, efficiency results
for the Brazilian municipalities show a clear relationship between the size of the municipality and its efficiency scores.
Indeed, under both DEA variants, smaller cities tend to be less efficient than larger ones hence indicating that the quality
of the frontier adjustment improves significantly as the size of the municipality increases. We present arguments that may
explain to some extent these findings, such as economies of scale and the excess spending due to revenue from royalties. However,
such effects require further, more careful examination. 相似文献

African leaders have not used processes in constitutional reforms that would result in institutions that could, in turn, reduce ethnicity (ethnic consciousness and mobilization for effective ethnic group demands on the state). Popular methods used to manage ethnicity have serious costs and weaknesses. Proposed are constitutional reforms via stable equilibrium determination processes. Focal points embedded in the cultures of the groups, relating to political institutions, distributive justice, and societal civility should facilitate the tasks. Important as enabling factors are leadership activities within civil society, inter alia to promote mutual respect, generalized trust, and pluralistic solidarity.

Hayek’s approach to cultural and institutional evolution has been frequently criticized because it is explicitly based on
the controversial notion of (cultural) group selection. In this paper this criticism is rejected on the basis of recent works
on biological and cultural evolution. The paper’s main contention is that Hayek employed group selection as a tool for the
explanation of selection among several equilibria, and not as a vehicle for the emergence of out of equilibrium behavior (i.e.,
altruism). The paper shows that Hayek’s ideas foreshadowed some of the most promising developments in the current literature
on the emergence of norms.

We study a class of single-server queueing systems with a finite population size, FIFO queue discipline, and no balking or reneging. In contrast to the predominant assumptions of queueing theory of exogenously determined arrivals and steady state behavior, we investigate queueing systems with endogenously determined arrival times and focus on transient rather than steady state behavior. When arrival times are endogenous, the resulting interactive decision process is modeled as a non-cooperative n-person game with complete information. Assuming discrete strategy spaces, the mixed-strategy equilibrium solution for groups of n = 20 agents is computed using a Markov chain method. Using a 2 × 2 between-subject design (private vs. public information by short vs. long service time), arrival and staying out decisions are presented and compared to the equilibrium predictions. The results indicate that players generate replicable patterns of behavior that are accounted for remarkably well on the aggregate, but not individual, level by the mixed-strategy equilibrium solution unless congestion is unavoidable and information about group behavior is not provided.JEL Classification: C71, C92, D81 相似文献

This study introduces new domestic mixed-asset and international equity securities that allow for exact portfolio replication even by small U.S. retail investors. Using these new series, various return characteristics are examined. Finally, three sets of mean-variance analyses are conducted: a domestic equity sector-only portfolio, a domestic mixed-asset portfolio, and an international mixed-asset portfolio. Real estate warrants inclusion to varying degrees in all three portfolios. International equity inclusion was also demonstrated. 相似文献

What Drives the Property Price-Trading Volume Correlation? Evidence from a Commercial Real Estate Market 总被引:2,自引:0,他引:2

The significant price-trading volume correlation found in the residential property market presents a challenge to the rational expectation hypothesis. Existing theories account for this fact with either capital market imperfection (down-payment effect or loss-aversion consideration) or imperfect information (search theoretic models). This paper employs data from a commercial real estate market, which face a different degree of severity of capital market constraint than the residential market, and thus provide an indirect but effective test for alternative theories. Policy implications are also discussed. 相似文献

Without a subprime market, some borrowers by virtue of poor credit history, unstable income, and other characteristics are unable to qualify for a mortgage. With a subprime market, there is a more complete credit supply schedule with the market pricing for poorer credit quality in the mortgage rate. By completing the capital market, subprime lenders reduce borrowing constraints. The result is a social welfare gain. Low-credit applicants otherwise denied funding are able to qualify by paying higher interest rates in exchange for offering more equity or lower loan-to-value ratios. This prediction is consistent with the subprime applicants financing or refinancing their mortgages at relatively low loan-to-value ratios. 相似文献

Internal Funds Allocation and the Ownership Structure: Evidence from Korean Business Groups 总被引:2,自引:1,他引:1
Byungmo?Kim Kooyul?JungEmail author In?Joon?Kim 《Review of Quantitative Finance and Accounting》2005,25(1):33-53
We examine the relationship between the controlling shareholder’s cash flow rights and the funds transfer in the internal capital market within Korean business groups (chaebols) during the period from 1998 to 2001. We find that the funds allocation in the firms where controlling shareholders have high cash flow rights is better aligned with the investment opportunities and therefore, more efficient than in the firms where they have low cash flow rights. This effect is stronger when they have controlling powers large enough to expropriate minority shareholders. However, during the financial crisis period, funds simply move toward the firms where controlling shareholders have high cash flow rights. The results evidence the tunneling behavior in the internal capital market within a chaebol that the ownership structure distorts the allocation of internal funds in such a way as to benefit the controlling shareholders.JEL Classification: G31, G30 相似文献

Theories on loan portfolio swap hedging are based on a portfolio-choice approach. This paper presents an alternative: a firm-theoretic model for bank behavior with loan portfolio swaps. Our paper derives the optimal loan rate and rate-taking loan amount of the banks portfolio, and relates them to the market loan rate, counterparty loan rate, swap default risk, capital-to-deposits ratio, and deposit insurance. We find that in the bilateral default risk approach, the comparative static results are generated by four factors: the banks risk magnitude about the equity market value, loan composition in the swap contract, the substitution effect in the loan portfolio, and the income effect from the swap transaction. The results imply that changes in the payoff asymmetry in the event of swap default and the banks regulatory parameters have a direct effect on the banks loan portfolio for lending and swap transactions.We would like to thank two anonymous referees for helpful comments and advice. 相似文献
