Investments and the holdup problem in a matching market

This paper studies the properties of the steady state equilibrium in a bilateral matching market with ex ante investments at the market entry stage. Investment incentives depend on search frictions because both parties in a match are partially locked-in when they bargain over the joint surplus from their sunk investments. The associated holdup problem is more important for the long side of the market. In the extreme case of perfectly substitutable investments only the agents on the short side make investments. When market frictions become negligible, the market equilibrium approaches the Walrasian outcome.     

Implementation of stable solutions in a restricted matching market

I analyze the admission mechanism used in Spanish universities. The system is open to strategic manipulation. This is because students are not allowed to express the whole list of available options. However, the mechanism implements the set of stable matchings in Nash equilibrium and the student's optimum in strong equilibrium. The mechanism also implements the students' optimum, in Nash equilibrium, under the class of “non-reverse” preferences. All these properties come from the fact that colleges do not have the opportunity to misrepresent their preferences. Received: 30 June 1995 / Accepted: 31 January 1997

Dynamics of price cooperating model in commodity market

For the problem of price fluctuation in the commodity market, some ordinary differential equation models are proposed and the stability of equilibrium price is studied. In this paper, we develop a mathematic model for price cooperation with diffusion and lag. When the economic parameters satisfy some conditions, the existence and stability of periodic price are investigated.     

Laissez-faire and the institutions of the free market

The absence of an adequate institutional structure explains why entrepreneurial capitalism did not automatically follow the collapse of central planning in the 1990s. It is a necessary function of a liberal state to provide a framework for the enforcement of private contractual terms. Beyond that basic need, other regulatory structures tend to emerge spontaneously through the force of mutual advantage and the test of social competence. In particular, institutions such as banking, the law, accountancy, insurance etc. exist to minimise the transactions costs which are inherent in a market economy.     

Escape dynamics and equilibria selection by iterative cycle decomposition

This paper explores the medium-run behaviour of bounded rational players in repeatedly played games when they occasionally experiment or make mistakes. The formal analysis introduces a hierarchical structure of limit sets to characterize the most possible medium-run behaviour over gradually increased time intervals. The paper refines the notion of stochastic stability and offers a precise measure of the speed at which stochastically stable equilibria occur. Finally, the paper applies the results to a 3×3 symmetric game of Young (1993).     

An analysis of firm and market volatility

In this paper, using time series data for the period 2 January 1998 to 31 December 2008 for 560 firms listed on the NYSE, we examine whether firm volatility is related to market volatility. The main contribution of this paper is that we develop an analytical framework motivating the firm-market volatility relationship. We present three new findings on volatility. First, we discover significant evidence of common volatility; for 12 out of 14 sectors, market volatility has a statistically significant effect on firm volatility for at least 50 percent of firms. Second, we discover significant evidence of size effects: for small-sized firms, there is weak evidence of commonality in volatility, while for large-sized firms there is high evidence (for as much as 75 percent of firms) of commonality in volatility. Third, we find that market volatility predicts firm volatility for firms belonging to five of the 14 sectors.

Labor market institutions and inflation volatility in the euro area

Despite having had the same currency for many years, EMU countries still have quite different inflation dynamics. In this paper we explore one possible reason: country specific labor market institutions, giving rise to different inflation volatilities. When unemployment insurance schemes differ, as they do in EMU, reservation wages react differently in each country to area-wide shocks. This implies that real marginal costs and inflation also react differently. We report evidence for EMU countries supporting the existence of a cross-country link over the cycle between labor market structures on the one side and real wages and inflation on the other. We then build a DSGE model that replicates the data evidence. The inflation volatility differentials produced by asymmetric labor markets generate welfare losses at the currency area level of approximately 0.3% of steady state consumption.     

House price risk and the hedging benefits of home ownership

Using a repeat-sales methodology, this paper finds that estimates of house price risk based on aggregate house price indices substantially underestimate the true size of house price risk. This is the result of the fact that aggregate house price indices average away the idiosyncratic volatility in house prices. Additional results show that the idiosyncratic risk exceeds the hedging benefits of home ownership. These results imply that for many home owners, owning a house may well add more price risk than it hedges away. These findings are based on a detailed dataset of individual housing transactions in the Netherlands.     

Location of industry, market size, and imperfect international capital mobility

This paper examines the impact of imperfect international capital mobility on an industrial location when increasing returns are present. When the international capital mobility is perfect, agglomeration of manufacturing firms progresses with a decline in transportation costs of manufactured goods, and full-agglomeration in a large-market country is observed at low transportation costs. In contrast, when international capital mobility is imperfect, agglomeration in a large-market country progresses with capital trade integration. When the transportation costs of manufactured goods are low, all capital holders in two countries invest their capital into a home market.

Sharing risk within and across countries: the role of labor market institutions

This paper studies the effect of labor market institutions on within- and cross-country risk sharing, using a model of international trade in risky assets modified to include a subset of agents, labor-owners who do not access financial markets, and employment security provisions. Labor market, institutions, by promoting within-country risk-shifting arrangements between agents with or without, access to financial markets, reduce the fluctuations of non-tradable labor incomes and amplify the, fluctuations of capital incomes. Capital flows become more volatile across countries, and if the, configuration of labor markets differs across countries, capital-owners bear the burden of systematic, undiversifiable world aggregate uncertainty.

Asymmetric information and term lending in the Euro money market: Evidence from the beginning of the turmoil

We address the role of information heterogeneity in the Euro interbank market for unsecured term lending. We use high-frequency quotes of bid and ask prices to estimate probabilities of informed trading for contract maturities from one month to one year. The dataset spans from November 2000 to March 2008, and includes the relevant events that characterize the developments of the euro area money market. We find that the probability of finding a trading counterparty with a wider information set has risen since the eruption of the turmoil. Our results also show that the probability of trading with a better-informed bank is higher on days when open market operations take place, and at the end of the maintenance period. This effect has strengthened during the turmoil. This suggests that the loose supply of money of the ECB has not dampened the distortions arising from asymmetric information in the unsecured money market.     

Value investing anomalies in the European stock market: Multiple Value, Consistent Earner, and Recognized Value

Empirical academic studies have consistently found that value stocks outperform glamour stocks and the market as a whole. This article extends prevailing research on existing value anomalies. It evaluates simple value strategies for the European stock market (compared to many other studies that test market data on a country-by-country basis) as well as sophisticated multi-dimensional value strategies that also include capital return variables (Consistent Earner Strategy) and momentum factors (Recognized Value Strategy), the latter reconciling intermediate horizon momentum and long-term reversals of behavioral finance theories. It can be shown that these “enhanced” value strategies can produce superior returns compared to returns of the whole market or “simple” value strategies without capturing higher risks applying traditional risk measures.

Questions about the equivalence of market rents and user costs for owner occupied housing

For modern nations, it is recognized as important that temporal and spatial variations in costs for comparable dwelling services are carefully measured. The costs of owner occupied as well as rental housing have important roles to play in both the consumer price index (CPI) and the System of National Accounts (SNA). The 1993 System of National Accounts (SNA93) specifies that a rental value of the housing stock should be included as part of the aggregates for personal consumption, personal income, income of proprietors and value added for the real estate industry. Yet, little attention has been devoted to an underlying commonality of practice: the implicit assumption that housing cost information for either renters or owner occupiers can be used for assessing movements over time and spatial differences in the cost of housing for both renters and owners, after allowing for differences regarding payment for taxes and certain ongoing expenses such as insurance and utilities. But in the real world, are the services that renters and owner occupiers get from their dwellings comparable? Also, for both renters and owner occupiers, are there place-related differences in the services they derive from their dwellings? And if so, what are the implications for official statistics making? These are the questions raised by the empirical results presented in this paper.
