How to measure innovation? New evidence of the technology–growth linkage

It is an undoubtful fact that economic growth depends, ultima ratio, on the production of new ideas. This article aims to contribute to the long-standing debate on the choice of the best proxy to measure innovation and technological diffusion, by offering alternative variables which are tested empirically by means of a panel dataset of 73 countries between 1980 and 2005. Two different proxies of technological progress (patents and a Intellectual Property Rights Index) are used to explain different growth rates of income per capita and, after controlling for endogeneity, our results suggest that both have a positive effect on innovation (and economic growth).     

Good research and bad teaching? A business school tale

The paper presents a simultaneous differential game between rich and poor Business Schools (BS) that yields an equilibrium in which either type of BS may end up with bad teaching and good research, without resorting to informational problems. The necessary condition for this is that the BS’s impatience is smaller than the growth rate of research, which may arise as a result of the school’s lack of vision and ambition in becoming a leading school, or due to the fact that after a given critical mass of human capital is achieved in a BS, research grows fast, making BS managers underuse the available human capital for teaching. Policy implications are discussed.     

An assessment of the equality of access and no-regulation approaches to next generation networks

The European Commission believes that for the regulation of next generation fixed telecommunications networks the continuity approach is preferable to the equality of access approach and the no-regulation approach. According to the European Commission, (i) functional separation eliminates discrimination and promotes competition, but should only be used as a measure of last resort because it involves various complex trade-offs, whereas (ii) the no-regulation approach fosters investment, at the cost of sacrificing competition. The article agrees that functional separation involves complex trade-offs but disputes the assertion that functional separation necessarily eliminates discrimination and promotes competition. In addition, the article also establishes conditions under which the no-regulation approach does not reduce competition.     

Assessing economic complexity as interindustry connectedness in nine OECD countries

Economic complexity can be defined as the level of interdependence between the component parts of an economy. In input–output systems interindustry connectedness is a crucial feature of analysis, and there are many different methods of measuring it. Most of the measures however, have important drawbacks to be used as a good indicator of economic complexity, because they were not explicitly made with this purpose in mind. In this paper, we present, discuss and compare empirically different indexes of economic complexity as intersectoral connectedness, using the inter-industry tables of nine OECD countries. According to most of the measures of connectedness large economies (USA, Japan) tend to be more complex than small economies (for example, Denmark). But if another type of measures is considered, the opposite conclusion is drawn, signalling a hidden characteristic of interdependence that so far has not been detected by conventional measures. This result should qualify the widespread idea that more interconnected productive structures propagate more intensely exogenous shocks and/or economic policy measures.     

Whites,Blacks, and <Emphasis Type="Italic">Brown</Emphasis> in the Labor Market in Brazil: A Study About Inequalities

This paper examines inequalities between white and black and brown populations in Brazil within occupations that require university degree. The main result confirms that once reached the university degree, blacks/brown usually obtain smaller but comparable income to that of whites. Although some racial discrimination in labor market may exist, such result corroborates other studies that identify schooling differentials as the main reason for the high income inequality found in Brazil.     

EXPLAINING RISING INEQUALITY: SKILL‐BIASED TECHNICAL CHANGE AND NORTH–SOUTH TRADE*

Abstract We review the ‘skill‐biased technological change (SBTC) versus North–South trade (NST)’ debate in order to explain widening wage inequality between skilled and unskilled workers. The traditional explanations based on exogenous SBTC and on the North–South Heckscher–Ohlin–Samuelson approach, as well as the early estimates that diagnosed a clear prevalence of the former, are firstly exposed and discussed. A presentation is then made of the recent theoretical literature that endogenizes SBTC, introduces new channels of impacts from NST, and combines both explanations. Finally, the current estimates show that (i) both explanations are relevant, (ii) their impacts differ according to industries and countries, (iii) outsourcing is the main vector of impact from NST and (iv) SBTC and NST interact.     

Short selling and stock returns: Evidence from the UK

The practice of shorting stocks was put forward as one of the causes of the recent financial crisis whereas Shiller (2003), for example, considers shorting an essential element of an efficient market. Shorting involves selling borrowed stocks and subsequently closing the position by purchasing and returning the stock to the lender. A profit will be realised if the stock's price decreases. Shorting enables investors who do not own a perceived overvalued stock to sell. Using a high-frequency UK dataset for the period between September 2003 and April 2010, our findings suggest shorting indicates evidence of overvalued stocks as significantly negative abnormal stock returns appear to follow an increase in shorting. These results do not hold, however, for shorting which occurs around the ex-dividend date. We further find that these results hold during the recent financial crisis.     

Can Experiences With a Country's Foods Improve Images of That Country?

ABSTRACT

This study examines how experience with other countries’ foods affects people's images of those countries, as well as the strength of such images. The findings show that foods are effective cultural elements that can enhance country images. People who have eaten a country's foods reveal more favorable country images than those who lack such experiences. Country images are even more favorable when people have more positive and many food experiences. Furthermore, positive country image effects are greater for people in opposite-hemisphere countries than for those in neighboring countries. Finally, people who prefer certain attributes of a country's foods provide more favorable ratings for related product attributes from that country, indicating affect transfer from food experiences to other product categories. These findings have key implications, especially for policy makers and researchers who seek effective ways to improve country images.     

Going West? Spatial polarization of the North Korean port system

This paper analyzes North Korean ports in light of existing models of port system evolution. It reviews the economic and political factors shaping port concentration in developed, developing, and socialist countries. A database on vessel movements allows for the analysis of individual North Korean port traffic by total capacity circulated, cargo type, fleet nationality, immediate origin and destination, and berthing time. While ideological factors and military control hamper port modernization and trade openness, traffic concentration at the Pyongyang–Nampo gateway highlights the spatial polarization in the capital region at the expense of Eastern ports for which inland transport limitations and industrial decline have become major issues. The North Korean case only partly fits general models because traffic concentration occurs due to geopolitical isolation and internal limitations rather than economic and trade growth.
