Trade protection and the role of non-tariff barriers

Review of World Economics - A growing share of modern trade policy instruments is shaped by non-tariff barriers (NTBs). Based on a structural gravity equation and the recently updated Global Trade...     

Ant colony optimization for the single model U-type assembly line balancing problem

An assembly line is a production line in which units move continuously through a sequence of stations. The assembly line balancing problem is defined as the allocation of tasks to an ordered sequence of stations subject to precedence constraints with the objective of optimizing a performance measure. In this paper, we propose ant colony algorithms to solve the single-model U-type assembly line balancing problem. We conduct an extensive experimental study in which the performance of the proposed algorithm is compared against best known algorithms reported in the literature. The results indicate that the proposed algorithms display very competitive performance against them.     

The impact of IQ and EQ on pre-eminent achievement in organizations: implications for the hiring decisions of HRM specialists

In this study, IQ and EQ determinants of pre-eminent achievement in organizations were explored to help HRM specialists in selecting more appropriate job applicants, having potential for outstanding performance in their career paths. Several EQ elements were proved the most important in the achievement. However, IQ elements still play a very important role in superior performance. Results also exhibit that correlation of IQ and EQ levels of superior performers is significant and strong. In conclusion, HRM specialists have to test both IQ and EQ in the hiring process, to create a high-performing workforce in their organizations.     

Financial flexibility,corporate investment and performance: evidence from financial crises

This study examines the impact of financial flexibility on the investment and performance of East Asian firms over the period 1994–2009. We employ a sample of 1,068 firms and place particular emphasis on the periods of the Asian crisis (1997–1998) and the recent credit crisis (2007–2009). The results show that firms can attain financial flexibility, primarily through conservative leverage policies and less commonly by holding large cash balances. Financial flexibility appears to be an important determinant of investment and performance, mainly during the Asian 1997–1998 crisis. In particular, firms that are financially flexible prior to this crisis (1) have a greater ability to take investment opportunities, (2) rely much less on the availability of internal funds to invest, and (3) perform better than less flexible firms during the crisis. Our analysis covering the credit crisis period of 2007–2009 suggests that some of the advantages of flexible firms towards investing persist but are significantly less pronounced over that period. We also find that the value of financial flexibility is region/country specific, which may be explained by the fact that different regions/countries often adopt different macroeconomic policies and operate in diverse economic/legal environments.     

Multidimensional goals of beef and dairy producers: an inter-industry comparison

The relative importance of seven goals were elicited for Louisiana beef and dairy producers using the fuzzy pair‐wise comparison method. Beef producers were more concerned with maintaining and conserving land, while dairy producers were more concerned with financial goals such as maximizing profit and avoiding years of loss or low profit.     

Nonlinearity and nonstationarity in international art market prices: evidence from Markov-switching ADF unit root tests

This study investigates the presence (or lack thereof) of nonlinear dynamics and nonstationarity in international art market prices using quarterly data for the period 1990–2011. We first test whether art market price indices follow stochastic trends or whether they are stationary by means of linear unit root tests. Next, we estimate the Markov regime-switching ADF model and test whether the linear or the nonlinear regime-switching model provides a better characterization of the global art market price series. We find that all art market price indices (except for Drawings) exhibit nonlinearity. To our knowledge, our study is the first one in the literature to suggest that a nonlinear (Markov regime-switching) model provides a better characterization of the behavior of price dynamics in international art markets. In particular, our findings indicate that the market for the overall global art market, paintings, old masters, sculptures, photographs, prints, and contemporary art might indeed be stationary while exhibiting nonlinear regime-switching properties. On the other hand, the market for drawings and the Nineteenth century art are found to be nonstationary. Overall, despite the common ground of a regime-switching framework, we still find that the sub-segments of the art market have their own inner regime switching dynamics and hence they can evolve differently overtime.     

Export Credit Guarantees and Export Performance: An Empirical Analysis for Germany

Recent literature finds that exporters are particularly vulnerable to financial market frictions. As a consequence, exports may be lower than their efficient levels. For this reason, many countries support exporters by underwriting export credit guarantees. The empirical evidence on the effects of those policies is, however, very limited. In this paper, we use sectoral data on export credit guarantees issued by the German government. We investigate whether those guarantees indeed do increase exports and whether they remedy the export‐restricting effect of credit market imperfections both on the sectoral and on the export‐market levels. Exploiting the sectoral structure of a rich three‐way panel data set of German exports, we control for unobserved heterogeneity on the country‐year, sector‐year and country‐sector dimensions. We document a robust export‐increasing effect of guarantees. There is some evidence that the effect is larger for export markets with poor financial institutions and in sectors that rely more on external finance.     

The impact of buyer–supplier relationships on supplier innovativeness: An empirical study in cross-border supply networks

Drawing on organizational learning and the relational view of the firm, this study seeks to understand the factors that drive supplier innovativeness in the context of cross-border supply relationships. To address this research objective, a survey included 189 parts and components manufacturers (suppliers) in Turkey; hierarchical regression analysis is used to test the hypotheses. The findings demonstrate that interfirm knowledge sharing routines, relation-specific investments, and governance mechanisms may promote supplier innovativeness by expanding the supplier's knowledge resources and encouraging it to invest in innovative activities. In addition, this research emphasizes differentiating effects of the supplier's tier position for the impacts of buyer assistance and cooperative tie. As such, this study contributes to the purchasing and supply management literature by empirically showing how buyer–supplier relationships, particularly in cross-border supply networks, affect supplier innovativeness.
