Sunspot fluctuations in dynamics with predetermined variables

Summary. In this paper, I study the existence of Sunspot Equilibria in a general framework whose dynamics allow for the presence of predetermined variables in the system. The main motivation for this research comes from the fact that previous studies did not allow for such predetermined variables which, nevertheless, appear quite naturally in economic models. I show, for a non-negligible subset of dynamics with predetermined variables verifying usual assumptions, the existence of Stationary Sunspot Equilibria fluctuating between an arbitrary finite number of states arbitrarily close to a steady state.

On wage- and profit-led demand regimes: learning from the evidence

Abstract

This paper contributes to the empirical research around the “wage-led” or “profit-led” demand regimes. It first reviews how Kalecki, and then Steindl, approached the relationship between economic growth and income distribution. Then, empirical analysis carried out under the probabilistic approach to econometric modeling shows statistical evidence, estimated through cointegration analysis, that in the long run, in three very open economies—Mexico, France, and Korea—the wage share is positively associated with demand and output. It finally discusses the macroeconomic dilemma that almost all countries have to face, i.e., a positive effect of a high-wage policy on demand and employment may diverge from a negative effect on output compatible with external equilibrium.     

On the risk premium in Nordic electricity futures prices

This paper examines empirically the relationship between electricity spot and futures prices, by analysing a decade of data for a set of short term-to-maturity futures contracts traded in the Nordic Power Exchange. It is found that, on average, there are significant positive risk premiums in short-term electricity futures prices. The significance and size of the premiums, however, varies seasonally over the year; whereas it is greatest during winter, it is zero in summer. It is also found that time-varying risk premiums are significantly related to unexpectedly low reservoir levels. Furthermore, before the unprecedented supply-shock that hit the market around the end of year 2002, the risk premiums were related to the variance and the skewness of future spot prices.     

The determinants of industrial location in Spain, 1856–1929

During the 19th century, the Spanish economy went through the early stages of the industrialisation process. This process developed in parallel to the growing market integration of goods and factors as a result of the liberal reforms and the construction of the railway network, with the subsequent fall in transport costs. In that period, there were major changes in the pattern of industrial location across Spain, with an increasing spatial concentration of industrial activities between the 1850s and the Spanish Civil War (1936–39) and a deeper regional specialisation. What were the forces behind these changes? On the theoretical side, the Heckscher–Ohlin model suggests that the spatial distribution of economic activity is determined by comparative advantage due to factor endowments. In turn, New Economic Geography models show the existence of a bell-shaped relationship between the process of market integration and the degree of concentration of industrial activity in the territory. This paper examines empirically the determinants of industrial location in Spain between 1856 and 1929 estimating a model that nests both Heckscher–Ohlin and NEG factors and tests the relative strength of these forces, since they are not mutually exclusive and might be at work simultaneously. The analysis of the results shows that both comparative advantage and NEG-type mechanisms were determinant drivers of industrial location in Spain, although their relative strength changed over time.     

Cross-Border Shopping: A Survey

The aim of this paper is to undertake a review of the most important literature on the phenomenon of fiscally induced cross-border shopping. Following the presentation of the principal theoretical models, the study concentrates on applied literature. Firstly, the elements common to the diverse applications are described, and then, a detailed analysis of the research undertaken into cross-border shopping for alcoholic drinks, tobacco, fuel, and lotteries is provided, concluding with a reference to the interaction between cross-border purchases and those effected over the internet. The results achieved by the empirical research coincide and support the principal result of the theoretical literature: the tax differentials between neighboring territories induce consumers to purchase in the territory where taxation is lower, on the condition that the tax saving compensates for the transport costs associated with the travel made by the purchaser in order to take advantage of the lower taxation.     

How do country‐level governance characteristics impact the relationship between R&D and firm value?

This article addresses the question of how country‐level governance characteristics moderate the market valuation of research and development (R&D). Using a valuation model and panel data from companies in the European Union, United States, and Japan, we find that effective corporate governance allows the market to better assess a firm's R&D investments. This finding is the conjunction with the effect of the legal system, the financial system, and mechanisms of control. First, as effectiveness of investor protection increases, the market valuation of R&D projects also increases. Second, more developed financial systems do a better job assessing R&D. Third, effective control mechanisms reinforce the positive effect of R&D on a firm's market value. In sum, our findings shed light on how policymakers can increase the benefits from firms' R&D spending and thus foster economic growth and social welfare using these country‐level governance characteristics.     

The taxation of capital returns in overlapping generations models

This paper shows that in the Diamond (1965) overlapping generations economy with production and capital savings, there is a period-by-period balanced fiscal policy supporting a steady state allocation that Pareto-improves upon the laissez-faire competitive equilibrium steady state (whether dynamically inefficient or efficient) without resorting to intergenerational transfers. The policy consists of taxing linearly (or subsidizing, in the dynamically efficient case) the returns to capital, while balancing the budget period by period through a lump-sum transfer (or tax, respectively) in second period. This intervention grants every generation the highest steady state utility attainable through markets (i.e. remunerating factors by their marginal productivities and without transfers) which under laissez-faire is not a competitive equilibrium outcome. A transition from the competitive equilibrium steady state to this other steady state is also Pareto-improving when the former is dynamically inefficient. The result disentangles from redistributive considerations the impact of the taxation of capital returns on steady state welfare, and thus provides a rationale for the taxation of capital returns that is based on efficiency considerations and not on redistributive goals.     

2009年政治危机对马达加斯加经济的影响

政治稳定对一国的经济增长起到决定性的作用。政治稳定和经济增长之间存在直接和间接的相关关系。2009年,马达加斯加(以下简称马国)的政治危机对其各个私人部门产生了不同的影响。其中旅游、纺织、建筑等行业受到政治不稳定的影响较为严重,其国内和国际市场也出现了衰退,进而导致该国经济水平的下降。公共投资的减少带来了公共工程项目的减少,包括建筑和基础设施项目的放缓。这次政治危机带来的负面影响是明显的,也是巨大的。
