The formation of money prices is a pervasive feature of market economies. The theoretical explanation of money prices requires economists to recognize that prices are the result of a cumulative process in which past prices and practices create present prices, which are the basis of the plans and actions that will create future prices and practices. Lavoie’s interpretive economics embraces the historical element in economic theory and furnishes an approach congenial to studying the market as a cumulative process.  相似文献

During the last 20 years, an important body of literature on the so-called ‘Ricardo’s 93% theory of value’ – the classical hypothesis which asserts that direct prices are very good predictors of both production prices and market prices – has shown that the hypothesized strong correlation in fact holds in the context of cross-sectional data. However, these empirical results are extremely dubious due to severe problems that cause indeterminacy and arbitrariness in the measures of correlation usually employed.   相似文献

Existence of persistent price dispersion suggests that some buyers find lower prices through search and information acquisition, while some sellers charge higher prices by gathering information on potential buyers. If buyers are not fully informed of the lowest price available in the market they end up paying a price higher than if they had full information. Similarly, if sellers are not fully informed about the highest price they could charge, they too suffer by receiving a price lower than had they had full information. This paper develops a hedonic price model that incorporates the effects of incomplete information on both sides of the market and obtains estimates of the discrepancies between market prices and buyers’ maximum willingness to pay and sellers’ minimum willingness to accept. Correlates of such price discrepancies are also explored. We apply the technique to a data set constructed from the American Housing Survey, and find that incomplete information has had a significant impact on housing prices.  相似文献

Price cap regulation is typically applied to natural monopolies operating with subadditive costs. Price caps are known to provide superior incentives for the regulated monopoly to pursue cost reduction and, in a multiservice/product context, undertake welfare enhancing price discrimination. It is well known that capping a Laspeyres index of the firm’s prices induces the monopoly to charge socially optimal “Ramsey” prices in the long run. This paper examines the suitability of the Laspeyres form of regulation when the regulated firm faces competition in the market for one of its services (outputs). We present the appropriately modified Ramsey pricing rule for the regulated dominant firm and demonstrate that capping a Laspeyres index of the dominant firm’s prices leads to prices that satisfy this pricing rule in the long run.  相似文献

In this project, our topic pertains to examination of market efficiency, employing data from closed-end funds (CEFs) trading in the American stock market. Employing both aggregate and individual data, we examine whether or not moderate market performance is a sufficient condition in order to achieve abnormal returns, in the short-run, through exploitation of discount deviations from its mean value. The main hypothesis tested is that market performance affects the mean-reverting properties of CEFs’ discount. Moderate market performance ensures the mean-reversion of CEFs’ discount and points to cointegration between the share prices of CEFs and their net asset value (NAV). Furthermore, when NAV is identified as the common stochastic trend of the system then, market inefficiency is detected.  相似文献

The purpose of this paper is to explore the effects of financial and currency indicators on wheat futures prices. The results suggest that the stock market, and particularly the S&P 500, positively influence the wheat market, a fact that is attributed to the wealth effect and the modern portfolio management in the context of international markets’ integration. There is also evidence that the energy markets affecting the supply and demand side exert significant impact on the wheat market. Furthermore, the results show that the shocks of the U.S. dollar/yen exchange rate are transmitted to the wheat market. Finally, the structural analysis of wheat prices’ volatility support the hypothesis of the asymmetric conditional variance, as it appears to be more volatile in response to positive shocks caused by higher wheat prices, contrary to the respective results of the equities market.  相似文献

This paper reports a new and significant experimental demonstration that market participants adjust their bids towards the price observed in previous market periods when—by design—individuals’ values should not be affiliated with the market price. This demonstration implies that market prices may not adjust as standard comparative statics predicts and emphasizes the significance of social aspects even in market contexts. Hence, the present study shows that market behaviour is not anomaly-free. Indeed, market behaviour does not reveal the underlying true preferences but rather context-dependent preferences.  相似文献

Suppose that a strong and a weak operator compete in a telecommunications market. To terminate a call operators need access to the competitor’s network if the call is off-net. Operators set two-part tariffs and price-discriminate according to termination of a call. Suppose as a benchmark that access prices are regulated at costs. I show that the weak operator’s profit and consumer welfare increase if the regulator sets a higher price to access the weak operator’s network. However, total surplus decreases even locally. *I received helpful comments from Mark Armstrong, Toker Doganoglu, Tommaso Valletti, Julian Wright, and, in particular, two referees and the editor Michael Crew. I gratefully acknowledge financial support from the Deutsche Forschungsgemeinschaft (Heisenberg Fellowship).  相似文献

Hourly data from the Spanish day-ahead electricity auction is used to obtain a lower bound measure of generators’ market power. Our method is not based on cost estimates but rather on the behavioral differences between strategic generators and more competitive producers. The results indicate that, despite the price cap effect of regulation in this market, the larger operators in the day-ahead market are able to increase significantly prices above the competitive benchmark. We also show that the two large generators do not exploit the full potential of their market power.  相似文献

The organized wholesale electric power markets in the United States are characterized by structural market power, and would not produce competitive results absent administrative intervention. Market power mitigation is a fundamental and permanent part of the market design for the organized wholesale electricity markets. Market power mitigation is essential to FERC’s policy of relying on competition to regulate electric wholesale power prices, consistent with its mandate under the Federal Power Act. Controversy has arisen about how to ensure that the markets clear on the basis of offers that have been determined to be competitive. Specifically, the issue is what institution and function is best situated to provide the initial critical determination about whether a participant’s offer is competitive. Despite recent clarification of FERC policies on the market monitoring function, the roles of market administrators and market monitors are a potential source of confusion and counterproductive institutional conflict. The FERC should refine and clarify its policy in this area by according exclusive responsibility to institutional, independent market monitors to monitor participants’ conduct and the potential for the exercise of market power through ex ante review of cost-based offers used in market power mitigation, subject to review by FERC.  相似文献

Economists know how to calculate optimal prices for electricity transmission. These are rarely applied in practice. This paper develops a 13-node model of the transmission system in England and Wales, incorporating losses and transmission constraints. It is solved with optimal prices, and with uniform prices for demand and for generation, re-dispatching when needed to take account of transmission constraints. Moving from uniform prices to optimal nodal prices could raise welfare by 1.3% of the generators’ revenues, and would be less vulnerable to market power. It would also send better investment signals, but create politically sensitive regional gains and losses.   相似文献

We present a simple model of trading in a financial market where agents are asymmetrically informed and information is transmitted through the price system. We characterize the equilibrium for this economy and show that ‘rational mispricing’ of assets occurs if the price system fails to reveal the insider information accurately. It is argued that the communication of wrong information through equilibrium prices is compatible with full rationality on the part of the investors and may explain deviations from the efficient markets hypothesis.  相似文献

We analyze the interaction between the incumbent’s incentive to upgrade the quality of its network and the entrant’s incentive to build a bypass network when the regulator sets a two-part access tariff to the incumbent’s network. Under this context, the entrant’s investment in a bypass network is delayed with a higher incumbent’s investment in quality. Moreover, the possibility of investment in a bypass network by the entrant has a positive effect on the incumbent’s incentive to upgrade quality. We show that a regulator cannot achieve the first best with a constant access tariff. If he wants to design an alternative welfare improving access tariff, he should set an access fee increasing (decreasing) in quality if the business-stealing effect of quality upgrades is weak (strong). The analysis suggests that if the entrant’s investment costs are declining or its market share is increasing over time, it is not always optimal to require the incumbent to lease facilities at cost-based prices.  相似文献

This paper analyses the impact of the EU Emissions Trading Scheme (ETS) on electricity prices, in particular on wholesale power markets across the EU. To study this impact, this paper discusses the major results of a bottom-up modelling analysis of the implications of emissions trading for the performance of the wholesale power market in 20 European countries. The analyses show that a significant part of the costs of (freely allocated) CO2 emission allowances is passed through to power prices, resulting in higher electricity prices for consumers and additional (‘windfall’) profits for power producers, even in cases of full auctioning. In addition, they show that the ETS-induced increases in power prices depend not only on the level of CO2 prices but also on the structure of the power market, i.e., the incidence of market power, and the price responsiveness of power demand. Finally, the analyses show that the internalization and pass-through of carbon costs are crucial elements in a policy regime to reduce CO2 emissions by both changing the mix of power generation technologies and lowering total electricity demand.  相似文献

In complete markets economies (Sandroni in Econometrica 68:1303–1341, 2000), or in economies with Pareto optimal outcomes (Blume and Easley in Econometrica 74:926–966, 2006), the market selection hypothesis holds, as long as traders have identical discount factors. Traders who survive must have beliefs that merge with the truth. We show that in incomplete markets, regardless of traders’ discount factors, the market selects for a range of beliefs, at least some of which do not merge with the truth. We also show that impatient traders with incorrect beliefs can survive and that these incorrect beliefs impact prices. These beliefs may be chosen so that they are far from the truth.  相似文献

The 1996 Telecommunications Act requires incumbent providers to lease network inputs to rivals at cost-based prices in order to jump-start competition. Sappington (Sappington, D. (2005). American Economic Review, 95(5), 1631–1638) uses the Hotelling model to show that input prices are irrelevant for an entrant’s decision to make or buy an input required for downstream production. We show that this result depends upon the particular model of competition employed. Specifically, input prices are not necessarily irrelevant in the Bertrand vertical differentiation model and are not irrelevant in the Cournot model. It follows that departures from cost-based input prices may distort entrants’ make-or-buy decisions in settings of practical interest.   相似文献

In this paper we report the findings of an economic experiment that examines the effects of an automated mitigation procedure (AMP) on prices and capacity investment choices of suppliers in a wholesale electricity market. Specifically, we examine the effects of different market power incentives on markets with and without an AMP. While we find that the AMP does not affect overall investment in capacity, the most significant determinant of long-run prices is investment in new capacity. The AMP also does not reduce long-run prices relative to markets without an AMP. Furthermore, our participants successfully manipulated the AMP’s trigger price. The data and a sample copy of the instructions are available upon request.

This paper presents a multi-sector model of tradable emission permits, which includes oligopolistic and perfectly competitive industries. The firms in oligopolistic industries are assumed to exercise market power in the tradable permit market as well as in the product market. Specifically, we examine the effects of the initial permit allocation on the equilibrium outcomes, focusing on the interaction among these product and permit markets. It is shown that raising the number of initial permits allocated to one firm in an oligopolistic industry increases the output produced by that firm. Under certain conditions, raising a “clean” (less-polluting) firm’s share of the initial permits can lead to reductions in both the product and permit prices. We discuss criteria for the socially optimal allocation of initial permits, considering the trade-off between production inefficiency and consumer benefit.  相似文献

The literature on the tragedy of the anticommons typically suggests that producers of complementary goods should integrate themselves. Recent decisions by the antitrust authorities seem however to indicate that there exists a tradeoff between the “tragedy” and the lack of competition characterizing an integrated market structure. In this paper we analyze such tradeoff in oligopolistic complementary markets when products are vertically differentiated. We show that quality leadership plays a crucial role. When there is a quality leader, forcing divestitures or prohibiting mergers, thus increasing competition, lowers prices and enhances consumer surplus. However, when quality leadership is shared, “disintegrating” firms may lead to higher prices. In this case, concerns about the tragedy of the anticommons are well posed in antitrust decisions.  相似文献
