Reemployment wages and UI liquidity effect: a regression discontinuity approach

This paper puts together the non-distortionary liquidity effect of unemployment insurance and job match quality. We identify a big impact on subsidized unemployment duration and a small impact on wages on the job that follows the unemployment spell. Wage gains are heterogeneous and concentrated on individuals at the bottom of the pre-unemployment income distribution. The non-distortionary nature of the liquidity effect reduces the pressure on low-income workers to accept lower productivity jobs.

运用久期模型进行利率风险管理的若干问题分析

利率的波动会给金融机构带来利率风险:重新定价风险和市场价值变动风险。传统的资产负债管理方法:缺口(gap)管理,只能解决前者而对后者无措。因而,后来理论界和业界并始广泛推崇和实行久期(duration)方法。久期充分考虑了与时间因素相关的现金流问题,可以同时兼顾利率变动对于收益和资本利得或损失的影响,从而实现利率免疫(interest immun ization)。巴塞尔委员会(2001年)推荐的监管银行利率风险的模型就是以久期模型为基础的。然而,也有些人认为该模型在金融机构资产负债管理中实际运用起来有种种困难,并对该模型提出了许多批评意见,本文将逐一分析这些问题及解决之道。     

Unobserved Heterogeneity,Exit Rates,and Re‐Employment Wages

Exit rates from unemployment and re‐employment wages decline over a period of unemployment, after controlling for worker observable characteristics. We study the role of unobserved heterogeneity in an economy with asymmetric information and directed search. We show that the unique equilibrium is separating and that skilled workers have more job opportunities and higher wages. The composition of the unemployed varies with the duration of unemployment, so average exit rates and wages fall with time. The separating equilibrium relies on performance‐related pay schemes and the ability of firms to commit to renting an input that is complementary to worker skills.     

Black–white wage differentials: duration and probability unemployment effects in a multiple of sample selection bias model

The extent to which probability and duration of unemployment affect the black–white wage differentials is examined in this paper. The paper simultaneously incorporates in the wage equation the multiple sample selection bias that occurs as a result of individuals’ propensity to be in the labor force, and the firm’s hiring decisions. The results reveal a substantial contribution of the duration of unemployment variable to the black–white wage differential, but a small portion of the differential is explained by the probability of unemployment. The results also indicate a sizeable difference between the contribution of the duration of unemployment variable to the male’s wage differentials (26%) and to the female’s (35%). The study finds that an individual’s labor force decision as well as a firm’s hiring decision are important in the wage determination process and that failure to account for the sample selectivity bias due to these two decisions will result in either underestimating or overestimating the wage differentials between black and white workers. At the macro level, the results seem to suggest that promotion of racial wage equality should be associated with policies that will minimize blacks’ incidence of unemployment and duration of unemployment spells.     

Patterns and Determinants of Price Changes: Analysing Individual Consumer Prices in Austria

Abstract. We provide empirical evidence on the degree and characteristics of price stickiness in Austria by estimating the average frequency of price changes and the duration of price spells from a large dataset of individual price records collected for the computation of the Austrian consumer price index. The mean (median) duration of price spells in Austria amounts to 14 (11) months, but there is considerable heterogeneity across sectors and products. We find that price increases occur only slightly more often than price decreases. For both directions, the average magnitude of price changes is quite large (11% and 14%, respectively). The introduction of the euro cash in January 2002 led to more frequent but, on average, smaller price adjustments than usual. Estimating the probability of a price change in a panel probit model, we find a small but positive effect of the price spell duration on the incidence of price changes. Furthermore, product‐specific inflation, the size and the sign of the last price change and the period of the euro introduction significantly affect the probability of a price change.     

Non-parametric analysis of poverty duration using repeated cross section: an application for Peru

Using repeated cross-section annual data for Peru spanning 2002–2011 and non-parametric duration analysis, our estimates support the hypothesis that both stay in and exit from poverty (non-poverty) depends on the duration and sequence of poverty (non-poverty) spells. We find that longer periods in poverty reduce the probability of leaving poverty and, conversely, longer periods spent out of poverty reduce the chance of falling back into poverty. Also, we show that, at least in the last decade (of high economic growth), the probability of staying in poverty was lower than staying in non-poverty and the probability of re-entering in poverty was higher than re-entering in non-poverty, being both differences growing with the number of accumulated spells. Past experiences of poverty and non-poverty seem to be essential to predict the future status of poverty.     

Buyer Search Intensity and the Role of the Residential Real Estate Broker

This study examines the impact of the real estate broker on the effectiveness of buyer search by focusing on the linkages between search intensity and the duration of search. How long a buyer searches depends on how sensitive the buyer is to within-period search costs and across-period, sequential search costs. High-income individuals and other homebuyers with high within-period search costs tend to search longer and less intensively. Buyers with high across-period search costs, such as out-of-town buyers, tend to search more intensively. Brokers, by reducing the opportunity costs of within-period search, increase buyer search intensity, which in turn reduces actual search time.     

What is an Investment Project's Implied Rate of Return?

How to measure a project's implied rate of return has long been an unresolved problem, except for some special cases. This paper derives return on present cost (ROPC) as the correct measure of an investment project's implied rate of return. The IRR is a biased measure except for projects classified as simple projects, and this bias is likely to be substantial in many real‐world applications. Thus while net present values should be used to determine whether to accept/reject projects, I recommend that analysts use ROPC in place of the IRR as a measure of a project's true rate of return.     

Environmental regulation,total factor productivity,and enterprise duration: Evidence from China

Environmental regulation has been confirmed to have an important impact on enterprise productivity, which is regarded as a crucial factor of enterprise duration. However, existing studies have paid little attention to how environmental regulation affects enterprise duration. Using firm‐level data from the Chinese Industrial Enterprises Database (2003–2007) and the stochastic frontier analysis method, we estimate enterprise total factor productivity (TFP) and its four decomposed components (scale efficiency change, technological change, factor allocation efficiency change, and technical efficiency change). Meanwhile, we adopt a comprehensive index to measure the environmental regulation intensity. Furthermore, we use the linear probability model and the proportional hazards model to investigate the effect of environmental regulation on enterprise duration through the mediating role of enterprise TFP. The results show that although environmental regulation per se negatively impacts on enterprise duration, environmental regulation can present a synthetic positive effect on enterprise duration due to its positive effect on enterprise TFP. Specifically, environmental regulation significantly mitigates the scale efficiency and technical efficiency of regulated enterprises. It also stimulates regulated enterprises' technological innovation and improves their factor allocation efficiency. In addition, state‐owned and large‐scale enterprises are more malleable when facing environmental regulations. We propose that the government should encourage enterprises to innovate and improve the allocation efficiency of production factors, so as to achieve the purpose of controlling environmental pollution in stages while extending enterprise duration.
