Spatial Comparisons of Poverty and Inequality in Living Standards in Malawi

The paper looks at poverty and inequality across areas in Malawi. The focus is on both monetary (consumption) and non‐monetary (health and education) dimensions of well‐being. Stochastic poverty dominance tests show that rural areas are poorer in the three dimensions regardless of poverty line chosen. Stochastic inequality dominance tests find that the north and south dominate the centre in health inequality, and there is no dominance between the north and south. With respect to education inequality, dominance is declared for the south‐centre pair only. A subgroup decomposition analysis finds that the south contributes the most to consumption and education poverty, while the centre is the largest contributor to health poverty. We establish that within‐area inequalities (vertical inequalities) rather than between‐area inequalities (horizontal inequalities) are the major driver of consumption, health and education inequality in Malawi.

成本节约的不确定性、效率抗辩与并购评估审查

横向并购可能给参与并购的企业带来成本节约而产生效率效应,同时也可能产生反竞争效应。在横向并购反垄断审查的效率抗辩中,并购企业只要能够证实成本节约的效率效应能够抵消反竞争效应进而增进社会总福利水平,就可以获得反垄断当局的批准。然而,成本节约及其实现程度具有不确定性,成本节约的不确定性不仅会影响消费者剩余和社会总福利水平,而且将对效率抗辩和反垄断当局并购审查的判定规则产生影响。本文以Cournot模型为基础,系统分析了成本节约的不确定性对于横向并购反垄断评估审查中效率抗辩、判定规则和预期消费者福利的影响,为反垄断当局在并购评估审查中如何考虑效率因素提供决策参考。     

Do high interest rates defend currencies during speculative attacks?

Do high interest rates defend currencies during speculative attacks? Or do they have the perverse effect of increasing the probability of a devaluation of the currency under attack? Drawing on evidence from a large sample of speculative attacks in developed and developing economies, this paper argues that the answer to both questions is ‘no’. In particular, this paper documents a striking lack of any systematic association whatsoever between interest rates and the outcome of speculative attacks. The lack of clear empirical evidence on the effects of high interest rates during speculative attacks mirrors the theoretical ambiguities on this issue.     

Reciprocity in Ranked Relationships: Does Social Structure Influence Social Reasoning?

Many economic and evolutionary theories have modeled cooperation as the evolutionary outcome of decisions made by autonomous, self-interested agents operating in a social vacuum. In this paper we consider the implications for cooperative interactions when prior social structures and corresponding social norms exist. In particular we investigate the influence of social rank/status on perceptions of fairness and tolerance of cheating. We review evidence from a series of experiments employing the Wason selection task (a test of conditional reasoning) and the ledger task (a decision making task) suggesting that people cued to adopt a perspective of high social rank are more tolerant of cheating and simultaneously believe that they have been more fairly treated (even when cheated) than people cued to adopt a perspective of low social rank. However, the evidence also suggests interesting cross-cultural differences in perceptions of fairness and tolerance of cheating in ranked relationships.

Comparison of Mean-Risk Efficient Portfolios in Asia-Pacific Capital Markets

In order to analyze the performance of mean-risk efficient portfolios, several methods of portfolio comparison have been developed. In this paper we analyze the second-order stochastic dominance efficiency of portfolios on the mean-risk efficient frontier assuming that the risk is represented by standard deviations and concordance matrices set up on the basis of Pearson's linear correlation, Spearman's rho, or Kendall's tau. Empirical analysis of the market returns of selected Asia-Pacific stock markets is carried out considering both the U.S. dollar and euro as reference currencies, and different periods: before and during the subprime crisis. Measures and portfolios on the mean-risk efficiency frontier that should be of interest to at least one risk-averse investor are empirically documented.     

The Momentum Effect in Latin American Emerging Markets

We find that momentum strategies yield profits in Latin American emerging markets. Both stock type and country play a major role in explaining the momentum effect in these markets, but stock type is much more important. For risk-averse investors, winner portfolios stochastically dominate loser portfolios in these markets, implying that there are no asset-pricing models consistent with risk-averse investors that can rationalize the momentum effect. The results obtained via the bootstrap procedure without replacement also uphold this conclusion.     

Convergence of Real Capital Market Interest Rates—Evidence from Inflation Indexed Bonds

This paper investigates the convergence of long‐term ex ante real interest rates (RIRs) obtained from Canadian, French, UK, and U.S. inflation indexed government bonds. In contrast to previous research, our evidence suggests full convergence in the long run and, hence, capital market integration. For the same sample period, global convergence is rejected for RIRs measured in conventional terms. From these results, we conclude that previous tests of the long‐run real interest rate parity might have suffered from weak measurement of real capital market interest rates.
