Social comparisons of wage increases and job satisfaction

We combine status quo and social comparison considerations and investigate whether relative wage increases in the sense of differences between individual wage increases and wage increases of comparable employees are related to managers’ job satisfaction. Using a panel data set of managers in the German chemical industry, we indeed find first evidence. The relation between relative wage increases and job satisfaction is relevant for managers with lower absolute wage levels in particular.     

Butler旅游地生命周期模型应用困境研究

Butler旅游地生命周期模型作为一个很有用的理论工具,虽然已被广泛应用于旅游地发展演化过程的研究之中,但在实际应用中也面临着一些不可忽视的困境。通过对Butler旅游地生命周期模型的分析发现,该模型在应用中存在以下难题：难以获得真实有效的历史数据,难以客观地对旅游地进行阶段划分,难以进行科学预测,难以适用于所有的旅游地。在上述分析基础上,认为科学统计旅游数据、全面参考旅游相关指标、注重研究空间的不同尺度、注意对未知因素的考虑等是化解上述困境的合理之道。

Financial market reactions to the overthrow and annexation of the Hawaiian Kingdom: evidence from London, Honolulu and New York

This paper investigates how financial market participants reacted to the US annexation of Hawaii in 1898 as well as prior events like the overthrow of the monarchy in 1893 and US tariff moves affecting Hawaii's sugar industry. The empirical work covers the trading of the Kingdom of Hawaii's major 1886 loan in both London and Honolulu as well as sugar company stock price reactions to annexation. The economic implications of US tariff policy moves, and the unfettered US market access promised by annexation, may well explain the continued uptrend in debt prices after the overthrow.

A structural break in the effects of Japanese foreign exchange intervention on yen/dollar exchange rate volatility

We study the impact of Japanese foreign exchange intervention on the volatility of the yen/dollar exchange rate since the early 1990’s in a GARCH framework with interventions as exogenous variables. Using daily intervention data provided by the Japanese Ministry of Finance, we show that the effect of interventions varies over time. From 1991 up to the late 1990’s, Japanese foreign exchange intervention is associated with an increase in volatility of the yen/dollar exchange rate. After the year 1997, Japanese foreign exchange intervention correlates with reductions in exchange rate volatility. This can be explained by the fact that Japanese foreign exchange intervention remained quasi unsterilized in the liquidity trap.

The Effect of Mortgage Price and Default Risk on Mortgage Spreads

Variations over time in mortgage yield spreads should reflect changes in the underlying prepayment option value; moreover, the relationship between mortgage yield spreads and interest rate dynamics should weaken as the value of the borrowers prepayment option declines. We verify this hypothesis through an empirical analysis of residential mortgage yield spread behavior, and we also present evidence that the strength of the relationship between mortgage spreads and interest rate dynamics weakens (strengthens) as the level of default risk increases (decreases). This result is consistent with the competing risks effect between a borrowers option to prepay or default. Our results demonstrate the importance of accounting for mortgage price discount to par as well as default risk when developing time series of mortgage yields.     

Bayesian Hypothesis Testing: a Reference Approach

For any probability model M={p(x|θ, ω), θεΘ, ωεΩ} assumed to describe the probabilistic behaviour of data xεX, it is argued that testing whether or not the available data are compatible with the hypothesis H₀={θ=θ₀} is best considered as a formal decision problem on whether to use (a₀), or not to use (a₀), the simpler probability model (or null model) M₀={p(x|θ₀, ω), ωεΩ}, where the loss difference L(a₀, θ, ω) –L(a₀, θ, ω) is proportional to the amount of information δ(θ₀, ω), which would be lost if the simplified model M₀ were used as a proxy for the assumed model M. For any prior distribution π(θ, ω), the appropriate normative solution is obtained by rejecting the null model M₀ whenever the corresponding posterior expectation ∫∫δ(θ₀, θ, ω)π(θ, ω|x)dθdω is sufficiently large. Specification of a subjective prior is always difficult, and often polemical, in scientific communication. Information theory may be used to specify a prior, the reference prior, which only depends on the assumed model M, and mathematically describes a situation where no prior information is available about the quantity of interest. The reference posterior expectation, d(θ₀, x) =∫δπ(δ|x)dδ, of the amount of information δ(θ₀, θ, ω) which could be lost if the null model were used, provides an attractive nonnegative test function, the intrinsic statistic, which is invariant under reparametrization. The intrinsic statistic d(θ₀, x) is measured in units of information, and it is easily calibrated (for any sample size and any dimensionality) in terms of some average log‐likelihood ratios. The corresponding Bayes decision rule, the Bayesian reference criterion (BRC), indicates that the null model M₀ should only be rejected if the posterior expected loss of information from using the simplified model M₀ is too large or, equivalently, if the associated expected average log‐likelihood ratio is large enough. The BRC criterion provides a general reference Bayesian solution to hypothesis testing which does not assume a probability mass concentrated on M₀ and, hence, it is immune to Lindley's paradox. The theory is illustrated within the context of multivariate normal data, where it is shown to avoid Rao's paradox on the inconsistency between univariate and multivariate frequentist hypothesis testing.
