Agglomeration economies and location choice: Foreign direct investment in Hungary1

Since the beginning of the transition process, Hungary has attracted a significant amount of foreign direct investment (FDI), although this is unevenly distributed among the twenty Hungarian counties. This paper examines the determinants of FDI at a regional level in Hungary and more particularly assesses the importance of agglomeration effects among determinants. A panel model of the location determinants of FDI in Hungary is developed and estimated. Empirical testing suggests that counties with higher labour availability, greater industrial demand and higher manufacturing density attract more FDI. Surprisingly, higher unit labour costs attract FDI. In addition, inter‐industrial agglomeration economies and infrastructure availability are found to be important.     

Technical efficiency and farm size: a conditional analysis

The relationship between technical efficiency and size might be affected by farm heterogeneity. We analyse this relationship conditional on a set of control variables. These control variables are chosen using a production model where technical efficiency is introduced as a parameter. As a result, technical efficiency affects both the input demand and the output supply of a profit maximising producer. The empirical application explores these issues using panel data of dairy farms in Spain.     

Can a Mixed Health Care System be Desirable on Equity Grounds?*

Should health care provision be public, private, or both? We consider this question in a setting where people differ in their earnings capacity and face some illness risk. We assume that illness reduces an individual's time endowment when waiting for treatment. Treatment can be obtained in a competitive private sector (through private insurance) or in the National Health Service (NHS) where it is provided free of charge but after some (endogenous) waiting time. The equilibrium in the health care sector consists of a waiting time in the NHS such that no patient wants to switch health care provider. This equilibrium is governed by two public policies: the income tax system and the size of the NHS. We find that: (i) a mixed system with a small NHS is never desirable; (ii) actuarially fair sickness insurance is never desirable either; (iii) a mixed system with a sufficiently large NHS may improve on a pure public system if the dispersion of earnings capacities is large enough; and (iv) the welfare gains from such a mixed system are not likely to be significant.     

Gains to Mutual Fund Sponsors Offering Multiple Share Class Funds

Although the number of mutual funds grew during the 1990s, much of the growth is attributable to the introduction of multiple share class (MS) funds. Proponents argue that the MS structure leads to cost savings, which can be passed onto investors as lower expenses. However, if the structure lowers costs, sponsors are likely to profit from it. Though investors are concerned about the base expense ratio, the sum of administrative and management fees, fund sponsors generate profits from the management fees. As such, they would prefer to increase the management fee if they can simultaneously lower administrative fees. Our results indicate that MS fund investors pay lower administrative fees, but management fees are approximately 7 basis points higher than single-class funds. Overall, base expense ratios are higher than for single-class funds, suggesting fund sponsors capture the cost benefits the MS structure provides. Our results are robust to different model specifications and different estimation techniques.     

Prices vs. Quantities: The Irrelevance of Irreversibility*

We explore the efficacy of price and quantity controls in a dynamic setup in which the decisions of some agents are irreversible. The assumption of irreversibility is shown to improve the performance of a tax relative to that of a system of tradable quotas and significantly alter the equilibrium behavior of agents. We nevertheless conclude that taking into account the fact that agents’ decisions may be irreversible does not lead to policy implications significantly different from those reached in a simpler model in which irreversibility is ignored.     

An Examination of the Differential Impact of Regulation FD on Analysts' Forecast Accuracy

Regulation fair disclosure (FD) requires companies to publicly disseminate information, effectively preventing the selective pre‐earnings announcement guidance to analysts common in the past. We investigate the effects of Regulation FD's reducing information disparity across analysts on their forecast accuracy. Proxies for private information, including brokerage size and analyst company‐specific experience, lose their explanatory power for analysts' relative accuracy after Regulation FD. Analyst forecast accuracy declines overall, but analysts that are relatively less accurate (more accurate) before Regulation FD improve (deteriorate) after implementation. Our findings are consistent with selective guidance partially explaining variation in the forecasting accuracy of analysts before Regulation FD.     

The effect of foreign ownership restrictions on stock price dynamics

The Effect of Foreign Ownership Restrictions on Stock Price Dynamics. —This paper uses Finnish data to explore the impact of foreign ownership restrictions on the dynamic properties of domestic stock prices. These restrictions create unrestricted stocks (foreign and domestic ownership) and restricted stocks (domestic ownership). Unrestricted share prices are significantly more volatile than those of restricted shares but their means are not significantly different from each other. The returns on the two types of shares are found to be generated by an error correction model. These results support the hypothesis that the unrestricted share prices tend to overshoot relative to equilibrium with the arrival of new information.     

Money Illusion and the Double Dividend in the Short Run

Abstract. In their seminal paper, Bovenberg and de Mooij (1994) elucidate why an ecological tax reform will not yield a double dividend, i.e. fails to increase the efficiency of the tax system. The present paper slightly modifies the Bovenberg and de Mooij model by introducing money illusion. With this modification, an environmental tax reform that raises the price level may generate a double dividend, since the additional tax on the dirty good does not reduce labor supply. A prerequisite for the double dividend to occur is a sufficiently small elasticity of substitution between clean and dirty consumption. Moreover, accounting for money illusion always reduces the intertemporal gross cost of the tax reform.     

Diffusion and spillover of new technology: a heterogeneous-agent model for cassava in West Africa

Understanding what determines the geographic spread of innovations can help guide the funding and implementation of research and extension programs. Our approach uses household survey data as model parameters, to simulate behavior across the entire surveyed population and avoid the aggregation bias associated with representative‐farm models. Such a “heterogeneous agent” approach allows us to infer the distribution of a technology's impacts across one set of households, and predict the potential for spreading to another set that shares similar characteristics with respect to natural resource endowments and farming systems. We apply the technique to new cassava varieties in West Africa, finding a strongly poverty‐alleviating impact, with substantial spillover potential from Nigeria to neighboring countries.
