A THEORY OF THE CROSS‐SECTIONAL FERTILITY DIFFERENTIAL: JOB HETEROGENEITY APPROACH

This article presents a theory of the cross‐sectional fertility differential, which produces the negative wage–fertility relationship based on job heterogeneity. Although evidence suggests the importance of job heterogeneity in the labor market, it has largely been ignored in theories of fertility choice. I show that a theory incorporating job heterogeneity requires only standard conditions on preferences to generate the negative wage–fertility relationship, and the negative relationship derived from the model is robust to changes in economic environments (e.g., public policy and technology). Furthermore, the theory reconciles the negative cross‐sectional wage–fertility relationship with various time‐series variations in aggregate fertility.     

CROSS‐SECTIONAL VARIATION IN INDIVIDUALS' EARNINGS INSTABILITY

There has been considerable recent interest in earnings instability—the variability of workers' earnings around their expected earnings paths. While previous work has measured trends in instability, often to illuminate trends in inequality, this paper investigates the variation across workers. Data from the Panel Study of Income Dynamics reveal considerable differences in earnings instability across demographic and occupational characteristics, generally in accordance with prior expectations. These results can also be used to develop a person‐specific measure of instability for use in behavioral studies, and it is shown that the resulting metric correlates strongly with several decisions that are plausibly influenced by earnings risk.     

PATENT POOLS AND CROSS‐LICENSING IN THE SHADOW OF PATENT LITIGATION*

This article develops a framework to analyze the incentives to form a patent pool or engage in cross‐licensing arrangements in the presence of uncertainty about the validity and coverage of patents that makes disputes inevitable. It analyzes the private incentives to litigate and compares them with the social incentives. It shows that pooling arrangements can have the effect of sheltering invalid patents from challenges. This result has an antitrust implication that patent pools should not be permitted until after patentees have challenged the validity of each other's patents if litigation costs are not too large.     

EXPLAINING ATTITUDES TOWARDS AMBIGUITY: AN EXPERIMENTAL TEST OF THE COMPARATIVE IGNORANCE HYPOTHESIS

Many theories have been put forward to explain attitudes towards ambiguity. This paper reports on an experiment designed to test for the existence of Comparative Ignorance when it is tested over events with a range of different likelihoods. A total of 93 subjects valued a series of gambles, one of which was played out for real. The results do not lend support to the theory, although the relationship between risk and ambiguity does appear to correspond with other theories and previous empirical work.     

政府研发资助促进企业创新的有效性:激励效应异质性假说与检验

关于政府研发资助能否促进企业研发创新活动以及在创新过程中如何更有效地发挥政府的作用,一直存在争议。本文基于理论分析,提出了政府研发资助促进企业创新的有效性以及激励效应存在异质性的假说,利用工业企业的创新活动数据检验了中国政府研发资助对企业研发创新活动的影响效应。总体来看,政府研发资助对企业自身研发投入存在激励作用,同时也会提升企业研发创新的专利和新产品的产出水平。政府资助的激励效应存在企业异质性,在企业规模越大、人力资本水平越高、劳动生产效率越高的企业中,政府资助的激励效应越大,并且对非国有企业的研发创新产出的促进效用要高于国有企业。另外,本文还发现科技活动的产出更多地依赖于研发人员的贡献。政府对企业研发创新进行资助时,应该根据企业具体的微观特征,制定针对性的资助方式,更有效地发挥政府资助的激励效应。     

OWN‐ AND CROSS‐PRICE ELASTICITIES FOR GAMES WITHIN A STATE LOTTERY PORTFOLIO

Lotto demand modeling typically focuses on a single game and evaluates whether estimated “effective price” (expected loss from buying one ticket) elasticity is consistent with net revenue maximization. However, a portfolio of several different lottery games is now usually offered to players and judging the effectiveness of agencies in generating revenue requires estimation of both cross‐price and own‐price elasticities. Here we employ data from Spain to derive elasticities. Results imply that games are under‐priced if net revenue maximization is the goal. But the cross‐price estimates suggest that the operator is successful in limiting the extent to which a large jackpot on one game cannibalizes same‐week sales of other games. The paper also analyzes the impacts from two increases in the level of entry fees introduced during the data period. These appear to have affected net revenue favorably.

THE EFFECT OF GOVERNMENT SPENDING ON ECONOMIC GROWTH: TESTING THE NON‐LINEAR HYPOTHESIS

Theoretical models suggest a non‐linear relationship between government size and long‐run economic growth. However, testing this hypothesis empirically in cross‐country studies is complicated by the endogeneity of government spending and the accurate identification of inflexion points. This paper examines the non‐linear hypothesis by incorporating threshold analysis in a cross‐country growth regression. The methodology utilizes a sample‐splitting framework and follows an objective strategy for identifying and testing changes in the slope. The results provide evidence in support of the non‐linear hypothesis for a broad panel of countries.     

ALLOWING FOR JUMP MEASUREMENTS IN VOLATILITY: A HIGH‐FREQUENCY FINANCIAL DATA ANALYSIS OF INDIVIDUAL STOCKS

Following recent advances in the non‐parametric realized volatility approach, we separately measure the discontinuous jump part of the quadratic variation process for individual stocks and incorporate it into heterogeneous autoregressive volatility models. We analyse the distributional properties of the jump measures vis‐à‐vis the corresponding realized volatility ones, and compare them to those of aggregate US market index series. We also demonstrate important gains in the forecasting accuracy of high‐frequency volatility models.     

FISCAL DECENTRALIZATION AND ECONOMIC VOLATILITY: EVIDENCE FROM STATE‐LEVEL CROSS‐SECTION DATA OF THE USA*

This paper examines the implications of fiscal decentralization for economic stability. It has been discussed that fiscal decentralization reduces the variance of GDP growth, due to the greater diversification of performance across jurisdictions. We examine this theoretical result using a panel data set of the 50 states of the USA over the period of 1992–1997. We show that the theoretical specification of the production function is supported. We also show a negative significant relationship between fiscal decentralization and economic volatility. The results are robust when we take into account the endogeneity of fiscal decentralization.     

CROSS‐COUNTRY CAUSES AND CONSEQUENCES OF THE 2008 CRISIS: INTERNATIONAL LINKAGES AND AMERICAN EXPOSURE

We model the causes of the 2008 financial crisis together with its manifestations, using a cross‐country multiple indicator multiple cause model. We consider both national and, critically, international linkages between countries and potential crisis ‘epicentres’, including the United States. A country holding an epicentre's securities is exposed through a financial channel, while a country that exports to that epicentre is exposed through a real channel. We are unable to find strong evidence that international linkages can be associated with crisis incidence. In particular, exposure to the United States in either form has little impact. If anything, it appears to help.     

CROSS‐COUNTRY TECHNOLOGY TRANSFER AND POLITICALLY DRIVEN INTERNATIONAL AGREEMENTS FOR ENVIRONMENTAL STANDARDS

Grossman and Helpman highlighted a political framework to internalize inefficiency incurred due to unilateral trade policy implementation by sovereign countries. This paper extensively adopts their framework to explore the effects of special interest politics on governments under negotiation to forge international environmental standards to control global emission. Particular attention is given to a case in which negotiation is driven by transferring the abatement technology. Within a specific factor model of international trade, improving the abatement efficiency through technology transfer can give the most mutually beneficial outcome, achieving the lowest level of global pollution compared to other political benchmarks.     

THE IMPACT OF DOMESTIC AND FOREIGN COMPETITION ON SECTORAL GROWTH: A CROSS‐COUNTRY ANALYSIS

This paper examines the impact of competition on the total factor productivity (TFP) of 21 manufacturing sectors in eighteen OECD countries over the period of time 1990–2006. We assume that the source of TFP growth can be either domestic or foreign innovation or technology transfer from the technological frontier. Trade openness, R&D, and human capital can have two effects: a direct effect on TFP (e.g., through innovation) and an indirect effect depending on the productivity gap between a given country and the technological frontier. We find that tougher domestic competition is always associated with higher sectoral productivity. Both import and export penetrations are positively associated with an increase of TFP. However, the channels through which higher TFP is materialized are different: export penetration works through level effect, while import penetration acts mainly when conditional on the level of technological development. The economical magnitude of the effect is not trivial.     

CROSS‐HEDGING OF EXCHANGE RATE RISKS: A NOTE*

This note studies the optimal production and hedging decisions of a competitive international firm that exports to two foreign countries. The firm faces multiple sources of exchange rate uncertainty. Cross‐hedging is plausible in that one of the two foreign countries has a currency forward market. We show that the firm's optimal forward position is an over‐hedge, a full‐hedge or an under‐hedge, depending on whether the two random exchange rates are strongly positively correlated, uncorrelated or negatively correlated, respectively.     

ADMINISTRATIVE CHANGE IN THE EU: A CROSS‐COUNTRY EMPIRICAL STUDY ON THE CONTEXTUAL DETERMINANTS OF NPM REFORM RHETORIC

Framed within the paradigm of New Public Management (NPM), structural reforms in the EU aimed at modernizing the public administrations of Member States (MSs) have long since been a priority area of the EU's economic policy. Since the 1990s, these reforms have been sharply intensified across European countries with the declared purpose of enhancing economy, efficiency and effectiveness in their national public sectors’ organizations. In line with the European Commission's recent research initiatives in search for novel quantitative data on NPM in the EU, this paper studies European parties’ NPM reform rhetoric. More specifically, it investigates the MSs’ institutional, economic and political context within which parties have declared their intention of reforming national administrative systems. Thus, it sheds light on the MSs’ domestic factors that are associated with the diffusion of the NPM values across the political discourse of EU's national parties.     

REGULATION AND RISK: A CROSS‐COUNTRY SURVEY OF REGULATED COMPANIES

This paper tests empirically whether regulation characterized by high incentives implies more risk to firms than regulation characterized by low incentives. Using a worldwide panel of 170 regulated companies operating in electricity, gas, water, telecommunication and transportation sectors during the period 1995–2004, I find that different regulatory regimes do not result in different levels of risk to their regulated firms. This result could be driven by a higher level of development of financial markets combined with a sophisticated diversifying behaviour of regulated firms.
