Growth in regions

We use a newly assembled sample of 1,528 regions from 83 countries to compare the speed of per capita income convergence within and across countries. Regional growth is shaped by similar factors as national growth, such as geography and human capital. Regional convergence rate is about 2 % per year, comparable to that between countries. Regional convergence is faster in richer countries, and countries with better capital markets. A calibration of a neoclassical growth model suggests that significant barriers to factor mobility within countries are needed to account for the evidence.     

Relating in business networks: Innovation in practice

Few studies have looked at the innovation process in the early stages of new business ventures in the context of business networks. Reporting on eight years of development of a new venture, we examine how the development of initial business relationships in an ever-changing business network affects technological innovation. We conclude that technological innovation is contingent on the development of business relationships that are a critical mechanism permitting a new venture not only to access but also to produce knowledge essential for innovating. For management this implies the need to strike a judicious balance between internal focus and closure to produce novel solutions and external focus and openness to experiment in business relationships.     

Monotone dependence in graphical models for multivariate Markov chains

We show that a deeper insight into the relations among marginal processes of a multivariate Markov chain can be gained by testing hypotheses of Granger noncausality, contemporaneous independence and monotone dependence. Granger noncausality and contemporaneous independence conditions are read off a mixed graph, and the dependence of an univariate component of the chain on its parents—according to the graph terminology—is described in terms of stochastic dominance criteria. The examined hypotheses are proven to be equivalent to equality and inequality constraints on some parameters of a multivariate logistic model for the transition probabilities. The introduced hypotheses are tested on real categorical time series.     

The Role of Beta and Size in the Cross-Section of European Stock Returns

This paper examines the ability of beta and size to explain cross-sectional variation in average returns in 12 European countries. We find that average stock returns are positively related to beta and negatively related to firm size. The beta premium is in part due to the fact that high beta countries outperform low beta countries. Within countries high beta stocks outperform low beta stocks only in January, not in other months. We reject the hypothesis that differences in average returns on size- and beta-sorted portfolios can be explained by market risk and exposure to the excess return of small over large stocks (SMB). Consistent with recent US evidence, we find that after controlling for size, there is no association between average returns and exposure to SMB.     

Restaurant Prices and the Mexican Peso

Of prime interest to border economies is exchange rate performance and currency valuation. Commonly used tools for this task include purchasing power parity (PPP) nominal benchmarks, and inflation-adjusted trade-weighted indices. The latter have the advantage of relying on commonly available international macroeconomic data but overlook microeeonomic information that may offer additional insight to issues surrounding exchange rate policy debates. Other efforts have utilized small samples of international product price comparisons to shed light on currency valuation questions. This paper develops one such tool by repeated sampling of prices charged for identical menu items sold at restaurant franchises in El Paso, Texas, and Ciudad Juárez, Chihuahua. A battery of statistical tests indicate that the international currency value of the peso consistently differed from the exchange rate implied by the border region restaurant price ratios in 1997, 1998, and 1999.     

POPULATION POLICY THROUGH TRADABLE PROCREATION ENTITLEMENTS*

One of the first tradable rights proposal is Boulding's (The Meaning of the Twentieth Century, London: George Allen and Unwin Ltd, 1964 ), dealing with overpopulation. We discuss both tradable procreation allowances and exemptions domestically and globally, to address underpopulation as well. We focus on three effects. Notably, the rights' tradability entails that whereas exemptions or expensive enough allowances benefit the poor, cheap allowances benefit the rich. A natalist policy also worsens the average education level of the next generation, whereas population control enhances it. Also, if procreation rights are grandfathered to countries, the scheme redistributes further. Our analysis suggests that procreation entitlements may be efficient in controlling population, without being necessarily anti‐redistributive.     

长期股权投资权益法核算下会计与税法的差异

由于我国实行的是税会分离模式,因此税法上在确定应纳税所得额和会计在确认利润的时候,二者之间必然有很多的差异,既有永久性的差异也有时间性的差异,长期股权投资权益法导致的差异比较难以把握,因为当会计对长期股权投资采用权益法核算的情况下从取得长期股权投资到最后的处置每一个环节都存在会计处理和税法规定不相一致的地方。     

Imperfect Competition in Auction Designs

We study the competition between two owners of identical goods who wish to sell them to a pool of potential buyers. The sellers compete simultaneously setting reserve prices for their second price sealed bid auctions. Upon observing the set reserve prices, the buyers decide simultaneously in which auction to bid. We show that this game has (at least) one equilibrium and that all equilibria are inefficient: reserve prices are not driven to zero (cost). We also discuss where and why the parallel between optimal auction design and optimal pricing in the case of monopoly breaks down for oligopoly.     

Environmentally oriented innovative strategies and firm performance in services. Micro‐evidence from Italy

This paper aims at analysing the impact of environmentally oriented innovative strategies on firms’ economic performance in terms of employment, turnover and labour productivity growth. We exploit a unique dataset of 773 Italian service firms with 20 or more employees, based on 1993–1995 Community Innovation Survey (CIS) II data on innovation strategies and 1995–1998 System of the Enterprise Account (SEA). Using a Gibrat‐like empirical model, our findings show a negative link between environmental motivations and growth in employment and turnover in the short term, which then associates to a not significant or even negative effect on labour productivity growth, a result which is explainable by various factors: non‐mature markets; early movers that need more time to grasp the benefits of innovative actions; weaknesses of some service branches. The effect on employment is in part compatible with the existing evidence and may be based on efficiency improvements (dematerialisation processes), which also impact on efficiency by reducing workforce numbers. The effect on turnover of environmental innovation strategy is negative, implying either a short‐medium effect, possibly balanced in the long run by net benefits in terms of higher added value, or a real negative impact, which may be contingent on the period of observation, when environmental strategies where not at the heart of strategic management policies. Neither Porter‐like effects nor virtuous circles among environmentally strategies and performance seem to be present, at least in the short run and for services firms, calling for the necessity of further analyses on medium‐ long‐term effects and performances of specific service branches. Though effects on performances could turn out positive in the long run when mature green markets and investments provide their benefits, our evidence highlights that services could still find hard times in tackling the well‐known low productivity ‘disease’ even in the environmental realm.
