The importance of the Logistics Performance Index in international trade

Logistics and transport increasingly play a pivotal role in international trade relations. The Logistics Performance Index (LPI) analyses differences between countries in terms of customs procedures, logistics costs and the quality of the infrastructure for overland and maritime transport. The aim of this article is to analyse the impact that each of these components has on trade in emerging economies using a gravity model. Furthermore, the study also attempts to detect possible advances in logistics in developing countries, which are grouped into five regions (Africa, South America, Far East, Middle East and Eastern Europe) by comparing the first LPI data published in 2007 with the most recent data, released in 2012. The results obtained reveal that improvements in any of the components of the LPI can lead to significant growth in a country’s trade flows. Specifically, LPI components are becoming increasingly important for international trade in many countries in Africa, South America and Eastern Europe.     

WHY ARE FERTILITY RATES AND FEMALE EMPLOYMENT RATIOS POSITIVELY CORRELATED ACROSS O.E.C.D. COUNTRIES?*

We develop a quantitative theory of fertility and labor market participation decisions in order to investigate the role of labor market frictions in generating the observed positive association between fertility and employment among O.E.C.D. countries. We find that unemployment induces females to postpone and space births, which, in turn, reduces the total fertility rate. Moreover, differences in female labor outcomes across the United States and Spain can account for the low fertility rate in Spain relative to the United States. We also find that labor market frictions can generate a positive association between female employment ratios and fertility rates across economies.     

Relationship between individualist–collectivist culture and entrepreneurial activity: evidence from Global Entrepreneurship Monitor data

This paper examines how one dimension of national culture (an individualist–collectivist orientation) is related to Total Entrepreneurial Activity, depending on the level of economic development, measured by GDP per capita. Researchers have traditionally associated individualism with high rates of firm creation, arguing that an orientation towards achievement and the pursuit of personal objectives (dominant aspects in individualist cultures) are determinants of entrepreneurial activity. The current analysis shows that a country’s culture correlates to entrepreneurship, but cannot uphold the idea that higher levels of individualism mean higher rates of entrepreneurship. Using data from the Global Entrepreneurship Monitor on 52 countries, the results show that a country’s entrepreneurship rate is negatively related to individualism when development is medium or low, and positively related to individualism when the level of development is high. Thus, individualism is not related to entrepreneurship in the same way in countries with differing levels of development.     

A two-stage sampling by unequal size samples from two normal populations with unknown variances

A two-stage procedure based on the statistic introduced by Scheffé (1943) to solve the Behrens-Fisher problem is considered in estimating the difference between the mean values of two normal distributions having unequal and unknown variances. Samples of unequal size are considered at each stage. A numerical example is given where the two-stage procedure is compared with the Satterthwaite (1946) approximate method.     

The structure and formation of business groups: Evidence from Korean chaebols

We study the evolution of Korean chaebols (business groups) using ownership data. Chaebols grow vertically (as pyramids) when the controlling family uses well-established group firms (“central firms”) to acquire firms with low pledgeable income and high acquisition premiums. Chaebols grow horizontally (through direct ownership) when the family acquires firms with high pledgeable income and low acquisition premiums. Central firms trade at a relative discount, due to shareholders’ anticipation of value-destroying acquisitions. Our evidence is consistent with the selection of firms into different positions in the chaebol and ascribes the underperformance of pyramidal firms to a selection effect rather than tunneling.     

Millenials’ intentions to book on Airbnb

ABSTRACT

The sharing economy has witnessed a significant growth in recent years, enhanced by the development of online platforms. In particular, Airbnb has witnessed a significant worldwide year-on-year growth. Given the importance and popularity of Airbnb, it is crucial to examine which factors affect intentions to book on this website. This study proposes and tests a model based on the Theory of Reasoned Action, to examine millennials’ determinants of intentions to book on Airbnb. Based on two online surveys targeting millennials from Germany and China, the results show that intentions to book on Airbnb is mostly influenced by subjective norm, desire for unique accommodation and variety, attitude and economic benefits. Surprisingly, economic benefits have the smallest effect. Perceived risk with the purchase channel was found to have no impact on intentions to book on Airbnb. Managerial implications and theoretical contributions are provided.
