Beyond the purchasing power parity: testing for cointegration and causality between exchange rates, prices, and interest rates

This paper reexamines the causality between the dollar and the yen in a multivariate framework with the aid of cointegration and error-correcting modeling for the 1951–94 period. The Phillips-Perron tests and Johansen's tests are performed. While causality from interest rates to exchange rates is found in the short run, no causality between prices and exchange rates is found in the short run. However, causality is found running from relative prices to exchange rates along with interest rates between the U.S. and Japan in the long run, which supports the long-run PPP hypothesis.     

政党与政权的生命

本文提出了一套关于一党制下的政权巩固理论，并试图利用该理论来解释一党制国家政权寿命长短不一的原因。文章作者认为，在政党建设过程中，政治精英们思忖如何建立强有力的政治支柱时，不得不考虑的两个因素就是反对派势力的强弱和寻租的难易程度。如果反对派势力越弱小，且寻租越容易，那么政权建设的成本就越低，但同时这又将不利于建立一个强大的政党联盟或政党组织，并最终导致一党制政权脆弱而不堪一击，一遇危机就陷入分崩离析的境地。相反，如果执政精英起初就面临强大的反对势力并且寻租的可能性很小，那么他们就会给潜在的盟友提供话语权和决策权，从而推动政党建设。事实也证明诸如此类的执政党在危机来临的时候有更强的柔韧性和生命力。为了证实该理论，作者以几内亚比绍和坦桑尼亚，印尼和菲律宾这两对国家为例进行了详细的阐述。     

FINANCING AND HOUSE PRICES

Recent empirical evidence on the effect of below-market financing on house prices has suffered from estimation and interpretation problems. In this paper, a methodology is developed to solve these problems. Using data for mortgage revenue bonds, the methodology is tested with results indicating that all financing subsidy is capitalized into house prices.     

Retail Leasing: The Determinants of Shopping Center Rents

The determinants of lease rentals are of fundamental importance to real estate researchers and practitioners. Retail leases are unique in that they typically have two rental components: a base rent and an "overage" rent equal to a percentage of the tenant's gross sales above some threshold level. In this paper, we develop and test a simple cash flow model of retail lease valuation that predicts that base rents are lower with higher percentage rent rates and are higher with greater threshold levels of sales. Using a sample of shopping center leases, regression analysis indicates that these tradeoffs are observed in the market.     

Values,beliefs, and welfare recipiency: Is there a connection?

Relationships between values/beliefs and welfare recipiency and work attachment are examined using a sample of black and white women. The concept of self-efficacy, i.e. perceived ability to produce and regulate events is used to model paths of influence between values/ beliefs and observable behaviors. No racial differences are found in the determinants of current labor force status and previous work history. Race is also found to have no significant impact on the probability of receiving public assistance. The explanatory power of measures of self-efficacy is found to be minimal with respect to receipt of public assistance or the duration of receipt of assistance.

Information and trade sizes: The case of short sales

In this study, we examine short selling of NASDAQ stocks and observe that more information about future returns is contained in small short sales than in medium-sized and large short sales, thus supporting the idea that NASDAQ short sellers stealth trade. These results are robust to different subsamples of stocks with and without tradable options and stocks that are more likely to face binding borrowing constraints. Further, these findings are contrary to the results in Boehmer, Jones, and Zhang (2008) who find that large NYSE short sales contain the most information. Combined, our study supports the idea that NASDAQ's bid test is less restricting than the NYSE's uptick rule and therefore attenuates the likelihood of stealth trading (Diether, Lee, & Werner, 2009a).     

What Do Rental Contracts Reveal About Adverse Selection and Moral Hazard in Rental Housing Markets?

This article examines the pricing of rental contracts for two types of renter households: those who are able to amass a large, up-front security deposit and those with little, or no, security to offer. Empirical tests are presented to suggest that, in dealing with renter households who have little, or no, security to offer, landlords earn at a similar rate of return as lenders who make riskier loans at a high interest rate to borrowers of dubious credit. The analysis suggests that this situation occurs in large part because of the problem of asymmetric information and moral hazard between landlords and renter households regarding the latter's use of the premises.     

Bias from Farmer Self‐Selection in Genetically Modified Crop Productivity Estimates: Evidence from Indian Data

In the continuing debate over the impact of genetically modified (GM) crops on farmers of developing countries, it is important to accurately measure magnitudes such as farm‐level yield gains from GM crop adoption. Yet most farm‐level studies in the literature do not control for farmer self‐selection, a potentially important source of bias in such estimates. We use farm‐level panel data from Indian cotton farmers to investigate the yield effect of GM insect‐resistant cotton. We explicitly take into account the fact that the choice of crop variety is an endogenous variable which might lead to bias from self‐selection. A production function is estimated using a fixed‐effects model to control for selection bias. Our results show that efficient farmers adopt Bacillus thuringiensis (Bt) cotton at a higher rate than their less efficient peers. This suggests that cross‐sectional estimates of the yield effect of Bt cotton, which do not control for self‐selection effects, are likely to be biased upwards. However, after controlling for selection bias, we still find that there is a significant positive yield effect from adoption of Bt cotton that more than offsets the additional cost of Bt seed.
