Employment instability,earnings and market structure

A model of incremental decision-making in local government is presented as an extention of that developed by davis et al. (1996) for US Congressional appropriation. This is then combined with joint supply and demand equation for local taxes and expenditure. An explicit Stone-Geary utility function derived when these fuctions are maximized subject to the supply and demand equations as constraints. Empitical results are then given for local authorities in England and Wales from 1974 to 1960. These results confirm a very important role for the bureauctic component within the overall tax-expenditure model.     

Export expansion and economic growth: Further empirical evidence

This paper examines the relationship between export expansion and economic growth in a sample of seventy-three developing countries, using data for the period 1960–1978. It shows that in both groups of low- and middle-income countries, export expansion is associated with better economic performance and that an important cause of this association is the favorable impact of exports on total factor productivity. The paper also demonstrates that the effect of commodity composition of exports on the relationship between export expansion and economic growth is substantial in more advanced developing economies.     

Public choice versus constitutional economics: A methodological interpretation of the Buchanan research program

Through conceptual redirections, the Buchanan research program attempts to react to the fact that economic policy advice is often ignored. In terms of positive analyses, the research perspective is focused on institutions, i.e., the rules of economic as well as political games. In terms of normative analyses, the democratic criterion of unanimous consent is substituted for the normative efficiency criterion employed by welfare economics. The underlying idea is to direct positive analyses toward developing informative explanations on which normative analyses can build in order to provide intellectual orientation and thereby to contribute to democratic self-enlightenment. However, large parts of the existing public choice literature can be regarded as empirically oriented welfare-economic analyses of the political sector. Consequently, they run the danger of duplicating the failure of economic policy advice. This is why, during the 80s James Buchanan has changed the name of his research program from public choice to constitutional economics.     

Export expansion and economic growth: Evidence from Chinese Provinces

This paper examines the effect of exports on economic growth based on the data of 30 Chinese provinces from 1978 to 1995. A theoretical model is based on the neoclassical production function, in which exports can affect output growth. It was found that the growth rate of exports and the growth rate of per capita output are positively related; i.e. provinces with faster growth of exports grew faster than the provinces with slower export growth. It was also found that investment in state enterprises was insignificantly related to output growth, while investment in private enterprises was positively related to growth.     

Export market correlation and strategic trade policy

In the traditional models of strategic trade policy pioneered by Brander and Spencer, exports of the domestic firm, engaged in a Cournot-Nash competition with the foreign firm in a neutral market, must be subsidized to maximize national welfare. We demonstrate that when the firms play the Cournot-Nash game in two stochastic and positively correlated markets, it may be optimal to tax exports to the more volatile market while subsidizing it in the other. The policy combination reduces the amplitude of aggregate profit and raises the utility of the risk-averse firm in a manner similar to the theory of portfolio choice. JEL Classification: F12, D18
Marchés d'exportation co-reliés et politique commerciale stratégique. Dans les modèles traditionnels de politique commerciale stratégique proposés par Brander et Spencer, les exportations de la firme nationale, qui est engagée dans une concurrence à la Cournot-Nash avec une firme étrangère dans un marché neutre, doit être subventionnée si l'on veut maximiser le niveau national de bien-être. On montre que, quand les entreprises jouent un jeu à la Cournot-Nash dans deux marchés d'exportation stochastiques et positivement co-reliés, il peut être optimal de taxer les exportations vers le marché le plus volatile et de subventionner les exportations vers l'autre marché. Cette combinaison de politiques réduit l'amplitude de variation des profits agrégés et augmente l'utilité de l'entreprise qui a une aversion au risque d'une manière qui ressemble à ce qui se passe dans la théorie des choix de portefeuilles.     

Export market participation with sunk costs and firm heterogeneity

In this article we investigate the importance of sunk costs, firm characteristics and spillovers from nearby exporters on a firm's decision to participate in exporting. The empirical analysis involves the estimation of a nonstructural, discrete choice, dynamic model with firm heterogeneity. By using panel data for Estonian companies from 1994 to 1999 we find that: (i) both sunk costs and observable firm characteristics are important determinants of export market participation; (ii) previous history matters, in that, if a firm has been exporting the previous period or the period before, it significantly increases the likelihood of the firm exporting in the current period; (iii) larger firms with high capital intensity and foreign ownership are more likely to be exporters; (iv) operating in an export-oriented industry increases a firm's likelihood of exporting.     

Endogenous growth,decline in social capital and expansion of market activities

We model in an endogenous growth set-up the hypotheses that the expansion of market activities weakens social capital formation and that firms can invest in formal mechanisms of control and enforcement to substitute for social capital (trust, work ethics, honesty). The model shows that the economy tends to grow faster when it is relatively poorer in social capital and that perpetual growth can be consistent with the progressive erosion of social capital. These results may help to reconcile Putnam's claim that social capital has declined in the U.S. with the satisfactory growth performance of the U.S. over the same period.     

Labor market reforms, job instability, and the flexibility of the employment relationship

We endogenize separation in a search model of the labor market and allow for bargaining over the continuation of employment relationships following productivity shocks to take place under asymmetric information. In such a setting separation may occur even if continuation of the employment relationship is privately efficient for workers and firms. We show that reductions in the cost of separation, owing for example to a reduction in firing taxes, lead to an increase in job instability and, when separation costs are initially high, may be welfare decreasing for workers and firms. We furthermore show that, in response to an exogenous reduction in firing taxes, workers and firms may switch from rigid to flexible employment contracts, which further amplifies the increase in job instability caused by policy reform.     

Horizontal market concentration: Theoretical insights from spatial models

This paper aims to further the study of horizontal mergers by reviewing the theory on spatial models that may be useful for their analysis. We examine the incentives conveyed by locations for undertaking merger and merger-related strategies, as well as the impact of the latter on strategic location choices. This literature review therefore focuses on the two-way relationship between horizontal market concentration and firm location.     

Parameter instability,stochastic volatility and estimation based on simulated likelihood: Evidence from the crude oil market

Stochastic volatility models with fixed parameters can be too restrictive for time-series analysis due to instability in the parameters that govern conditional volatility dynamics. We incorporate time-variation in the model parameters for the plain stochastic volatility model as well its extensions with: Leverage, volatility feedback effects and heavy-tailed distributed innovations. With regards to estimation, we rely on one recently discovered result, namely, that when an unbiasedly simulated estimated likelihood (available for example through a particle filter) is used inside a Metropolis-Hastings routine then the estimation error makes no difference to the equilibrium distribution of the algorithm, the posterior distribution. This in turn provides an off-the-shelf technique to estimate complex models. We examine the performance of this technique on simulated and crude oil returns from 1987 to 2016. We find that (i): There is clear evidence of time-variation in the model parameters, (ii): Time-varying parameter volatility models with leverage/Student's t-distributed innovations perform best, (iii): The timing of parameter changes align very well with events such as market turmoils and financial crises.     

The riegle-neal act and local banking market concentration

The Riegle-Neal Interstate Banking and Branching Efficiency Act of 1994 greatly transformed the American banking system by allowing the widespread establishment of interstate bank branching networks. This paper examines possible effects on local banking market concentration that resulted from the provision in the Riegle-Neal Act that allowed states to opt-in to the establishment of de novo interstate branches. Regression analysis using data from more than seven hundred cities does not provide any evidence that allowing the establishment of de novo interstate branches caused increases in local banking market concentration. These results may help alleviate some concerns that passage of the Financial Services Regulatory Relief Act currently pending in Congress will result in lessened competition in local banking markets. The author would like to thank discussant Janice Breuer and other participants of the International Atlantic Economic Conference, held in Quebec City from October 16–19, 2003 for helpful comments and suggestions. The author would also like to thank Trevor Lyon for his valuable research assistance.     

The effects of competitors on new product launch and market expansion in the hybrid car market

This paper evaluates the effect of competitors on automakers’ new product launch and market expansion decisions in the hybrid car market. Using data from the entire history in US hybrid car market from 2000 to 2014, this paper estimates a Poisson model with endogeneous switching to account for the initial launch and the following expansion decisions. The results indicate that the presence of competing brands’ hybrid vehicle models has a net positive effect on a brand’s initial launch and expansion decisions. This suggests that demand expansion and market learning from competitors’ hybrid model launch and consumer cultivation are very important for this relatively new technology. Further, I find that the impact of competitors varies over time, vehicle origins, and classes.

出口卡特尔与反垄断的法律探讨

出口卡特尔是出口商之间设定价格同盟以及建立排他性出口销售渠道的横向协议.为了鼓励出口,维护本国利益,世界各国反垄断法普遍对本国出口卡特尔予以反垄断"豁免",而对外国出口卡特尔则依据"合理原则"认定其是否危害本国竞争环境,并进行相应制裁.我国的反垄断法应当限制国外出口卡特尔,同时应明确对国内出口卡特尔的"豁免".     

出口产品质量、出口关系存续与增长

本文检验了我国企业出口产品质量提升对企业出口关系存续及其增长率的影响。研究结果表明:企业出口产品质量升级有利于企业出口关系的存续,并能够提升其出口增长率。稳健性检验显示,更换产品质量测算方法、样本区间、计量方法等并不影响本文基本结论,且在考虑了内生性问题后,本文基本结论依然不变。从影响机制来看,产品质量升级通过增强消费者偏好提高了企业出口关系存续概率,通过增强消费者偏好以及提高出口价格促进了出口增长率提升;同时,产品质量升级还通过提高企业出口关系存活概率进一步促进了企业出口增长率的提升。最后,异质性检验结果显示,出口产品质量提高对外资企业和出口到高收入国家的企业出口关系存续的积极影响较大,而对私营企业和出口到低收入国家的出口增长率的积极影响较大。     

Toward the crisis: a Kaleckian-Keynesian interpretation of the instability of growth and capital accumulation in Brazil

This article examines theoretically and empirically the instability of Brazilian investment and growth for the past couple of decades, highlighting the evolution that led to the current crisis. A theoretical discussion highlights the importance of Kaleckian and Keynesian approaches in understanding the semi-stagnation of the Brazilian economy since the 1990s. Empirical evidence shows that investment has increased until 2013, but not to the point of getting the economy back on the track of high growth rates and higher investment-GDP ratios. The econometric findings are compatible with the theoretical underpinnings of investment activity based on Keynes and Kalecki and suggest the existence of room for activist policies in Brazil in order to stimulate economic activity.     

Optimal Export Taxes, Welfare, Industry Concentration, and Firm Size: A General Equilibrium Analysis

By using an imperfect-competition model, it is shown that an export tax, optimal in partial equilibrium, is upwardly biased and may not be optimal in a general equilibrium setting with free entry/exit. It is shown also that the export tax has an ambiguous impact on firm size. The results of an applied general equilibrium model for the Turkish economy suggest that the export tax estimated with the PE formula is larger by a small factor than the computed export tax. However, the export tax leads to an increase in firm size and, most importantly, to a social welfare loss.     

Stock and credit market expansion and economic development in emerging markets: further evidence utilizing cointegration analysis

This paper empirically investigates the relationship between equity and credit market development and economic growth, in a sample of five very important ‘emerging’ markets. In particular, employing a multivariate time-series methodology to test for long-run trends and causality between variables that proxy for stock market development, credit market development and economic development. The results seem to suggest that equity markets have a role to play only in relatively liberalized economies, like Chile and Mexico. In financially repressed economies, like India, the equity market does not affect real sector growth. Furthermore, the banking crises in the 1980s and 1990s in Chile and Mexico resulted in a negative relation between economic growth and the credit market. In South Korea, equity and credit markets both affect economic growth, but not vice versa. In countries where the nature of the stock market has been speculative, like Taiwan, a negative relationship is detected between equity market development and economic development.
