Stochastic convergence of the catch-up rate and multiple structural breaks in Asian countries

Allowing for multiple structural breaks and cross-section dependence, we re-investigate the hypothesis that the catch-up rates stochastically converge for 13 Asian countries from 1960 to 2007. Non-rejection of stationarity provides evidence for stochastic convergence, implying that following shocks to the catch-up rate, it will eventually revert to its long-run level.     

ECB repo rate setting during the financial crisis

I estimate a reaction function for the ECB using an ordered logit model for the period 1999-2009. Allowing for a smooth transition from one set of parameters to another, I detect a rapid change in the middle of 2008.     

Allocative efficiency measurement with endogenous prices

In the nonparametric measurement of allocative efficiency, output prices are fixed. If prices are endogenous, the overall output in the market determines the allocative efficient point. We develop an alternative semi-nonparametric model that allows prices to be endogenously determined.     

Investigating regional house price convergence in the United States: Evidence from a pair-wise approach

In this paper we examine long-run house price convergence across US states using a novel econometric approach advocated by Pesaran (2007) and Pesaran et al. (2009). Our empirical modelling strategy employs a probabilistic test statistic for convergence based on the percentage of unit root rejections among all state house price differentials. Using a sieve bootstrap procedure, we construct confidence intervals and find evidence in favour of convergence. We also conclude that speed of adjustment towards long-run equilibrium is inversely related to distance.     

How effective is European merger control?

This paper applies an intuitive approach based on stock market data to a unique dataset of large concentrations during the period 1990–2002 to assess the effectiveness of European merger control. The basic idea is to relate announcement and decision abnormal returns. Under a set of four maintained assumptions, merger control might be interpreted to be effective if rents accruing due to the increased market power observed around the merger announcement are reversed by the antitrust decision, i.e. if there is a negative relation between announcement and decision abnormal returns. To clearly identify the events' competitive effects, we explicitly control for the market expectation about the outcome of the merger control procedure and run several robustness checks to assess the role of our maintained assumptions. We find that only outright prohibitions completely reverse the rents measured around a merger's announcement. On average, remedies seem to be only partially capable of reverting announcement abnormal returns. Yet they seem to be more effective when applied during the first rather than the second investigation phase and in subsamples where our assumptions are more likely to hold. Moreover, the European Commission appears to learn over time.

Country-of-origin effects and antecedents of industrial brand equity

Does the country-of-origin effect matter to industrial brand equity in international business-to-business (B2B) markets? The effect of a product's country-of-origin (COO) on both industrial buyers' and consumers' perceptions and evaluations has been one of the most widely studied phenomena in the fields of international business, marketing, and consumer behavior since the 1960s. Although many country-of-origin studies focus on consumer behavior in developed countries and acknowledge that the processes and stages of economic development by which consumers use COO information may differ in developing countries, the fact that there has been little research to investigate the effects of COO could explain the variations in international buyers' evaluations of industrial brand equity in the newly-industrialized economies, such as Taiwan. Taiwanese firms are now formidable global B2B market players by successfully transforming themselves from manufacturing mainly low-value and labor-intensive goods to producing many high value-added products that require advanced technology, equipment and significant business expertise. With the adoption of advanced technology and equipment, an important question is whether unique and innovative fastener products from Taiwan have generated the country-of-origin effects in international B2B buyers' minds. The main finding is that the country-of-origin of fasteners has not yet become an important antecedent of industrial brand equity in the case of the fastener industry in Taiwan.

The multiple effects of carbon values on optimal rotation

Non-consumptive benefits which increase with crop age, like keeping carbon sequestered, lengthen optimal rotation compared with rotation for timber alone. High proposed carbon prices may extend rotation indefinitely. Carbon storage in wood products reduces this tendency. Biomass as an energy source displacing fossil fuels favours rotations near those of maximum biomass productivity. Use of sawn timber to displace structural materials with high embodied carbon favours somewhat longer rotations. Effects of rotation on soil carbon, and fossil carbon volatilised in harvesting operations, are further complications. Including all carbon effects results in optimal rotations somewhat longer than those based only on timber value, but shorter than those based on timber plus forest carbon. To include all factors intuitively is not possible: balanced appraisal needs economic calculations.
