Equilibrium and matching under price controls

The paper considers a matching with contracts model in the presence of price controls. The model contains two important streams in the matching literature, those with and those without monetary transfers, as special cases. An adjustment process that ends with a stable outcome is presented. The paper presents a notion of competitive equilibrium, called drèze equilibrium, and shows drèze equilibrium allocations to be equivalent to allocations induced by stable outcomes. We therefore have an equivalence that is valid with and without monetary transfers as well as when monetary transfers are limited

The Impact of Rent Controls in Non-Walrasian Markets: An Agent-Based Modeling Approach

We use agent-based models to consider rent ceilings in non-Walrasian housing markets, where bargaining between landlord and tenant leads to exchange at a range of prices. In the non-Walrasian setting agents who would be extramarginal in the Walrasian setting frequently are successful in renting, and actually account for a significant share of the units rented. This has several implications. First, rent ceilings above the Walrasian equilibrium price (WEP) can affect the market outcome. Second, rent ceilings that reduce the number of units rented do not necessarily reduce total market surplus. Finally, the distributional impact of rent controls differs from the Walrasian setting.

Pricing and trust

We experimentally examine the effects of flexible and fixed prices in markets for experience goods in which demand is driven by trust. With flexible prices, we observe low prices and high quality in competitive (oligopolistic) markets, and high prices coupled with low quality in non-competitive (monopolistic) markets. We then introduce a regulated intermediate price above the oligopoly price and below the monopoly price. In monopolies volume increases and so does quality, such that overall efficiency is raised by 50%. Somewhat surprisingly, the same pattern emerges in oligopolies. In fact, across all market forms transaction volume and traded quality are maximal in regulated oligopolies

Markov Equilibria in Dynamic Matching and Bargaining Games

Rubinstein and Wolinsky (1990) show that a simple homogeneous market with exogenous matching has continuum of (non-competitive) perfect equilibria, but the unique Markov perfect equilibrium is competitive. By contrast, in the more general case of heterogeneous markets, we show there exists a continuum of (non-competitive) Markov perfect equilibria. However, a refinement of the Markov property, which we call monotonicity, does suffice to guarantee perfectly competitive equilibria, if, and only if, it is monotonic. The monotonicity property is closely related to the concept of Nash equilibrium with complexity costs

Property taxation as incentive for cost control: Empirical evidence for utility services in Norway

Cost control in the public sector is a challenge for political institutions. Theoretical research recently has shown incentive effects of property taxation that can work as a mechanism to hold costs down. We are able to investigate the empirical relevance of this proposition, since local governments in Norway represent a kind of natural experiment where about 30% of them have residential property tax. The framework of the analysis is a bureau producing public services for the local government, and control of slack is related to the budget constraint of the bureau. High costs are understood as the result of an agency problem. In a stylized model of this interaction, we show that property taxation increases the local government budget responsiveness to higher costs if housing demand is not ‘too’ elastic. Both complimentarity between service supply and housing demand and migration equilibrium contribute to the negative relationship hypothesized between the property tax base and the reported costs of the bureau. The econometric analysis confirms significant differences in unit costs dependent on tax structure. Existence of property taxation seems to help overcome the agency problem and reduce costs. The potential problems of endogeneity of the choice of property taxation and unequal comparisons are handled with instrument variables and matching.

Pro-rata matching and one-tick futures markets

We find and describe four futures markets where the bid-ask spread is bid down to the fixed price tick size practically all the time, and which match counterparties using a pro-rata rule. These four markets´ offered depths at the quotes on average exceed mean market order size by two orders of magnitude, and their order cancellation rates (the probability of any given offered lot being cancelled) are significantly over 96 per cent. We develop a simple theoretical model to ex- plain these facts, where strategic complementarities in the choice of limit order size cause traders to risk overtrading by submitting over-sized limit orders, most of which they expect to cancel

House price momentum and strategic complementarity

House prices exhibit substantially more momentum, positive autocorrelation in price changes, than existing theories can explain. I introduce an amplification mechanism to reconcile this discrepancy. Sellers do not set a unilaterally high or low list price because they face a concave demand curve: increasing the price of an above-average-priced house rapidly reduces its sale probability, but cutting the price of a below-average-priced house only slightly improves its sale probability. The resulting strategic complementarity amplifies frictions because sellers gradually adjust their price to stay near average. I provide empirical evidence for concave demand using a quantitative search model that amplifies momentum two- to threefold

Pricing and Trust

We experimentally examine the effects of flexible and fixed prices in markets for experience goods in which demand is driven by trust. With flexible prices, we observe low prices and high quality in competitive (oligopolistic) markets, and high prices coupled with low quality in non-competitive (monopolistic) markets. We then introduce a regulated intermediate price above the oligopoly price and below the monopoly price. The effect in monopolies is more or less in line with standard intuition. As price falls volume increases and so does quality, such that overall efficiency is raised by 50%. However, quite in contrast to standard intuition, we also observe an efficiency rise in response to regulation in oligopolies. Both, transaction volume and traded quality are, in fact, maximal in regulated oligopolies.markets; price competition; price regulation; reputation; trust; moral hazard; experience goods

Globalization and Imperfect Labor Market Sorting

This paper focuses on the ability of the labor market to correctly match heterogeneous workers to jobs within a given industry and the role that globalization plays in that process. Using matched worker-firm data from Sweden, we find strong evidence that openness improves the matching between workers and firms in export-oriented industries. This suggests that there may be significant gains from globalization that have not been identified in the past – globalization may improve the efficiency of the matching process in the labor market. On the other hand, we find no evidence that openness affects the degree of matching in import-competing industries. These results remain unchanged after adding controls for technical change at the industry level or measures of domestic anti-competitive regulations and product market competition. In addition, we find no evidence that technical change has any impact on the degree of matching at the industry level. Our results are also robust to alternative measures of the degree of matching, openness, or the trade status of an industry.Matching, Globalization, Firms, Workers, Multinational Enterprises, International Trade
