Real interest rates: nonlinearity and structural breaks

Real interest rate is a crucial variable that determines the consumption, investment and saving behavior of individuals and thereby acts as a key policy tool that the central banks use to control the economy. Although many important theoretical models require the real interest rates to be stationary, the empirical evidence accumulated so far has not been able to provide conclusive evidence on the mean reverting dynamics of this variable. To resolve this puzzle we re-investigate the stochastic nature of the real interest rates by developing unit root tests for nonlinear heterogeneous panels where the alternative hypothesis allows for a smooth transition between deterministic linear trends around which stationary asymmetric adjustment may occur. When the newly developed panel unit root tests are applied to the real interest rates of the 17 OECD countries, we were able to uncover overwhelming empirical support in favor of mean reversion in the short-run and long-run real interest rates. Therefore, these results show that the conclusions drawn from a miss-specified test that ignores the presence of either nonlinearity, structural breaks or cross sectional dependence can give quite misleading results about the stochastic behavior of the real interest rates.     

The presence of unemployment hysteresis in the OECD: what can we learn from out-of-sample forecasts?

This paper investigates the relevance of unemployment hysteresis in seventeen OECD countries. We employ an out-of-sample forecast exercise in which a mean-reverting autoregressive model is compared to an autoregressive model with an imposed unit root. A substantial difference in forecasting performance between the two models is established for many countries, but the results are mixed in their strength. The evidence for unemployment hysteresis in Austria, Finland, Iceland, Israel, Italy, Japan and Sweden is, however, convincing. For no country can unambiguous support for a mean reverting unemployment rate be found.     

Corruption,growth, and growth volatility

While the existing studies focus on the corruption–growth relationship, this paper introduces a new focus involving corruption and growth volatility. The Ehrlich–Lui (1999) framework provides the theoretical background of the paper, which produces testable hypotheses regarding the corruption–growth and the corruption–growth volatility relationship. The cross-section dataset that is used in the empirical analysis contains 121 developed and developing countries. In terms of the relationship between the governance-related variables and growth rates, only corruption control and government effectiveness significantly and adversely affect the average growth rate. Regarding the relationship between growth volatility and governance-related variables, the results suggest that higher corruption control, expropriation risk control, government effectiveness, and government consumption decrease growth volatility.     

Business Ethics Research with an Accounting Focus: A Bibliometric Analysis from 1988 to 2007

This article uses bibliometric analysis to empirically examine research on business ethics published in a broad set of journals, focused over the period 1988–2007. We consider those journals with an emphasis on accounting. First, we determine the citation frequencies of documents to identify the core articles in accounting research with an ethics focus as well as the contributions of influential fields included in the research sphere of these journals. We also employ document co-citation analysis to analyze the scholarly communication patterns that exist within the realm of the specified articles. Second, we utilize social network analysis tools to profile the centrality features of the co-citation network of these documents.     

Explaining Eastern Germany's Wage Gap: The Impact of Structural Change

Since Eastern Germany's conversion to a market economy wages have remained considerably below the West German wage level. This article looks at the role of establishment-specific factors—such as sectoral affiliation and size of the labour force—in this process. A non-parametric decomposition that has played a prominent role in the gender wage gap literature is applied to breakdown the East–West wage gap into its constituent components. Using establishment data from German employment statistics, the article demonstrates that the catching-up process of Eastern Germany's wage level is hindered by the shift in its economic structure towards lower-paying types of companies, which has caused the lagging behind in the adjustment of wages.     

The stability of the Turkish Phillips curve and alternative regime shifting models

This article, presents empirical evidence supporting instability of the Phillips curve in Turkey. We employ the multiple structural break models and the Markov-switching models and then evaluate the performance of the two models. The data pertain to the monthly inflation rate in Turkey for the period of 1987 to 2004. The results show that the Turkish Phillips curve is not linear. There exists no evidence on the asymmetry in the inflation response to output gap. The persistence of inflation is found to be much lower than in linear models. After 2001, slight decline in persistence of inflation is observed. There exits weaker support for the Phillips curve for the periods where the policymakers attempt to take the advantage of the tradeoff between output and inflation relationship.     

The Innovation Process and the Development of a Sustainability Strategy

ABSTRACT

This article analyzes what influences a firm's choice of strategy—why some firms stick to defensive strategies while others rely on offensive ones. With this in mind a survey was conducted on mineral sector companies associated with the Brazilian Mining Institute. The results show that the majority of companies use an offensive strategy and that some companies use more than one strategy at the same time. That is, they possess a corporate strategy and a sustainability strategy.     

The influence of internet customer reviews on the online sales and prices in hotel industry

In this paper, the impact of two service quality metrics (star rating and customer rating) on hotel room sales and prices is investigated. Two of the most popular tourist destinations in the world, Paris and London, are chosen. It is found that a higher customer rating significantly increases the online sales of hotels. The study results show that a 1% increase in online customer rating increases Sales per Room up to 2.68% in Paris and up to 2.62% in London. Contrary to expectations, higher stars do not increase the sales. It is also shown that higher customer ratings result in higher prices of the hotel and the prices of high star hotels are more sensitive to online customer ratings.     

Entry to foreign markets and productivity: Evidence from a matched sample of Turkish manufacturing firms

We examine the effects of international trading activities of firms on creating productivity gains in Turkey by using a recent firm-level data set over the period 2003–2010. We establish treatment models and investigate the productivity improvements of firms through trade by using propensity score matching techniques together with difference-in-difference estimates. Three different groups of treatment are constructed: (1) firms that are involved only with import activities, (2) firms that are involved only with export activities and (3) firms that are involved with both export and import activities. The results of the study suggest that both exporting and importing have positive significant effects on total factor productivity (TFP) and labour productivity (LP) of firms. Importing is found to have a greater impact on productivity of firms compared to exporting. Further, two-way trade is found to have more significant effects than those of one-way trade on firm productivity. Finally, our results indicate that international trade has greater impact on LP rather than TFP of firms.     

浅析我国增值税税制改革的发展与完善

我国现行增值税制度存在征税范围窄、税率偏高、企业税负不公平等一系列问题,因此,必须对现行增值税制度进行改革与完善。应扩大增值税的征税范围,并适当降低税率,逐步由“生产型”增值税转变为“消费型”增值税。
