This paper analyzes how the use of endogenous direct advertising affects the functioning of a horizontally-differentiated market. We formulate a two-stage game of pricing and informative advertising in which two firms, first, compete with mass advertising and, later, build a database using their historical sales records and compete by directly targeting the ads on their potential customers. We show that, compared to the case where firms only use mass advertising, direct advertising yields higher advertising efforts and an intertemporal reallocation of both market power and profits from the first to the second period. We also find that targeting increases the overall firms’ profit and the level of social welfare, but the impact on the average intertemporal price and consumer surplus is ambiguous. Finally, when reaching the potential market with mass advertising is sufficiently expensive, the use of direct advertising leads firms to provide the socially optimal level of advertising whereas, if mass advertising is cheap, firms tend to launch too little advertising in the first period and too much in the second. 相似文献

Pulse Fishing and Stock Uncertainty 总被引:1,自引:0,他引:1

Large variation in stock dynamics affects the accuracy of stock estimates, which fisheries managers rely on when determining quotas and other regulations. The purpose of this paper is to investigate the implications of uncertainty on pulse fishing. We show that as the variance of the random natural fluctuations increases, the optimal pulse length decreases and converge toward a constant-escapement policy. Hence, in fisheries with large natural variability, a constant-escapement policy is a good approximation of the optimal policy. 相似文献

Policymakers use both extrinsic and intrinsic incentives to induce consumers to change behavior. This paper investigates whether the use of extrinsic financial incentives is complementary to intrinsic incentives, or whether financial incentives undermine the effect of intrinsic incentives. We conduct a randomized controlled trial that uses information interventions to residential electricity customers to test this question. We find that adding economic incentives to normative messages not only does not strengthen the effect of the latter but may reduce it. These results are consistent with recent theoretical work that suggests a tension between intrinsic motivation and extrinsic incentives. 相似文献

We consider a vertical relationship where an upstream monopolist supplies input to downstream duopolistic firms. Under the assumption that downstream firms produce under a soft capacity restriction, we show that the balance between price and quantity in downstream firms’ strategy is endogenous. In this way, the monopolist’s charge for input co-determines downstream market conduct. We spell out some consequences of this, for example, that an increase of downstream capacity costs can result in increased output. We discuss other implications in relation to pass-through and incidence of cost changes. 相似文献

This paper analyses the relationship between the size of adjustment costs and the intensity of labor market flows. I argue that high adjustment costs inhibit adjustment to temporary shocks, leaving adjustment to long-lived shocks unchanged. Worker turnover is also reduced because of the negative impact that adjustment costs have on churning.Received: January 2002, Accepted: November 2002, JEL Classification:

Abstract. Researchers have used stylized facts on asset prices and trading volume in stock markets (in particular, the mean reversion
of asset returns and the correlations between trading volume, price changes and price levels) to support theories where agents
are not rational expected utility maximizers. This paper shows that this empirical evidence is in fact consistent with a standard
infinite horizon – perfect information – expected utility economy where some agents face leverage constraints similar to those
found in todays financial markets. In addition, and in sharp contrast to the theories above, we explain some qualitative differences
that are observed in the price-volume relation on stock and on futures markets.
We consider a continuous-time economy where agents maximize the integral of their discounted utility from consumption under
both budget and leverage constraints. Building on the work by Vila and Zariphopoulou (1997), we find a closed form solution,
up to a negative constant, for the equilibrium prices and demands in the region of the state space where the constraint is
non-binding. We show that, at the equilibrium, stock holdings volatility as well as its ratio to stock price volatility are
increasing functions of the stock price and interpret this finding in terms of the price-volume relation.

I examine the effect of reform on telecom performance using a second-generation regulatory framework index and panel data techniques to test how regulatory governance affected sector performance in 22 Latin American countries during the period 1980–1997. Sound regulatory governance in telecommunications has a positive impact on network expansion and efficiency, in both the static and dynamic specifications. Openness of markets to competition and divestment of former state-owned telco operators also contributed positively to better sector performance. The dynamic specification shows that past performance has its own strong effect on present (and perhaps future) performance. 相似文献

Summary. Although not assumed explicitly, we show that neutrality plays an important role in Arrow and other impossibility theorems. Applying it to pivotal voters we produce direct proofs of classical impossibility theorems, including Arrow's, as well as extend some of these theorems. We further explore the role of neutrality showing that it is equivalent to Pareto or reverse Pareto, and to effective dictatorship for non-null social welfare functions satisfying the principle of independence of irrelevant alternatives. It is also equivalent to Wilson's Citizens' Sovereignty--which is related to the intuition that symmetry over alternatives makes social preference depend only on citizens' preferences. We show that some of these results are more fundamental than others in that they extend both to infinite societies and to considerably smaller domains of preferences. Finally, as an application of Arrow's theorem, we provide a simple proof of the Gibbard-Satterthwaite theorem.Received: 13 April 2000, Revised: 6 December 2002, JEL Classification Numbers:
D71, C70.I thank Salvador Barberá, Luis Corchón, Cesar Martinelli, Eric Maskin, Tomas Sjöström, Ricard Torres, José Pedro Ubeda, and an anonymous referee for feedback. The proofs of Arrow's theorem and two Wilson's theorems come from a note I wrote in 1987 at Universitat Autónoma de Barcelona (Ubeda [16]). In 1996 Geanakoplos [7] wrote a proof of Arrow's theorem similar but not identical to mine. All work in this paper is independent of his. 相似文献

Tests of unit roots and other nonstationary hypotheses that were proposed by Robinson (1994) are applied in this article
to the Nelson and Plosser's (1982) series. The tests can be expressed in a way allowing for structural breaks under both the
null and the alternative hypotheses. When applying the tests to the same dataset as in Perron (1989), we observe that our
results might be consistent with those in Perron (1989) when testing the nulls of trend-stationarity or a unit-root. However,
we also observe that fractionally integrated hypotheses may be plausible alternatives in the context of structural breaks
at a known period of time.

Using cross-country cross-industry data, this paper explores how industry’s growth in number of firms in Central-East Europe (CEE) region is influenced by bank concentration in both the pre-crisis and crisis periods. The CEE region shows highly concentrated banking markets and less-developed financial markets; thus, the level of bank concentration and the resulting credit supply are crucial for firm creation and survival. Despite this, there is little evidence on these countries in the literature. Our empirical results suggest an inverted-U relationship: industry growth is fostered by bank concentration, but there is a turning point from which higher concentration begins producing the opposite effect. Moreover, the positive impact has a greater intensity during the crisis period compared to the pre-crisis period. Between sectors’ analysis shows that high-tech sectors are less reactive to changes in the concentration level. 相似文献
