ABSTRACT

Economists’ solution to the tragedy of the commons relies on well-defined property rights and competitive market mechanism for limiting individuals’ self-serving, short-sighted actions that result in a dramatic depletion of the common resources. However, this solution implicates a serious threat in terms of sustainability. Recently, deterioration of genetic diversity reached alarming levels, mainly attributed to escalating economic pressure that obliges farmers to shift from local breeds towards more profitable and more productive industrial breeds. This study empirically examines the efficiency of the free market mechanism as a solution to the tragedy of the commons through a unique natural experiment in which a huge demand shock arises regarding sheep. Results robustly show that the free market mechanism can cope with even a very challenging demand shock through the adjustment of prices without any shortage of the commodity. However, this finding does not guarantee that such an outcome is sustainable over the very long term. Analysis of the growth rate of the local sheep breeds population and cross-breed sheep population shows that the trend is overwhelmingly in favour of cross-breeds, thus supporting concerns for a free market mechanism, intrinsically driving the extinction of local sheep breeds, an invaluable genetic resource.  相似文献

Several studies have assessed stock market under- or overreaction of stocks and there is some agreement among them. However, there is much disagreement about what constitutes market underreaction or overreaction, and the conditions that cause it. The substantial variation in results among studies may be partially attributed to the types of firms that are contained in any sample. We investigate this premise by focusing on a sample of technology stocks that experienced an extreme change in stock price, along with a corresponding control sample of non-technology stocks that experienced a similar extreme change in stock price on the same day.

Based on the subsequent stock price behavior of each sample, we find a greater degree of overreaction within extreme positive changes in technology stock prices (winners) than in non-technology stock prices. In addition, we find a greater degree of underreaction within extreme negative changes in technology stock prices (losers) than in non-technology stock prices. When considering winners and losers collectively for technology and non-technology firms, it appears the market is overoptimistic when it initially revalues technology stock prices relative to non-technology stock prices.

The degree of under- or overreaction of technology stocks varies within the sample of technology stocks, and is conditioned on firm-specific characteristics. Overall, our results suggest that technology stocks exhibit unique stock price behavior subsequent to an extreme change in price, and that this unique behavior can even vary among technology firms according to firm-specific characteristics.  相似文献

Abstract

I investigate the central principle that underlies the OECDs tax base erosion and profit shifting initiative. The principle claims that (corporate) profits should be taxed where economic activities deriving the profits are performed and where value is created. First, I argue that its plausibility depends on establishing that states have an entitlement to the productive factors in their territory, and therefore to a share of the value created by employing those factors. Second, I maintain that this cannot presently be established. If states fail to discharge duties requiring wealth redistribution, they do not have an unqualified right to the productive factors in their territory. Even if they are not subject to such duties, states can only legitimately claim a share in the fair value of the goods created. I show that given widespread exploitation in global value chains, the market prices of (intermediary) goods do not reflect their fair value.  相似文献

Abstract

In the analysis of ‘justice’ in market exchanges, the scholastic doctors made some contributions to the theories of prices and money. But probably the most important (and neglected) contribution lies in the domain of anthropology, i.e. in the explanation of human nature and human behaviour. In this paper the authors are going to work out two scholastic ideas that provide an alternative to the individualist and utilitarian approach of neoclassical economics. (1) Persons are morally ruled beings; a sense of ‘duty’ is a key element in their behaviour; (2) Persons are social beings competing and cooperating to achieve certain goals. Dominant positions and privileged information grant them special powers that should not be abused.  相似文献

Abstract

Objective: This article aims to compare market prices (i.e., third-party reimbursement and patient co-payment) of one-piece and two-piece colostomy, ileostomy and ureterostomy appliances in Belgium, Denmark, England and the Netherlands in 2005.

Methods: Data were collected through contacts with health authorities, health insurance companies, manufacturers, industry associations and distributors. The price difference between Belgium and another country was expressed as a proportion of the Belgian price.

Results: A total of 64 out of the 72 ostomy appliance products considered were cheaper in Belgium. Prices of one-piece colostomy appliances and two-piece ileostomy appliances were consistently lower in Belgium. The highest prices of ostomy appliances were observed in the Netherlands. Sixteen out of 20 products and 21 out of 25 products were more expensive in Denmark and England, respectively, than in Belgium. Colostomy appliances were more expensive in England than in Belgium.

Conclusions: Market prices varied substantially between countries, indicating that manufacturers adapt their pricing strategy to the policy environment existing in the ostomy appliance market of each country. Also, there appears to be scope for reducing prices in some countries.  相似文献

In a symmetric differentiated experimental duopoly we test the ability of Price Matching Guarantees (PMG) to raise prices above the competitive levels. PMG are introduced both as a market rule (the selling price is always the lowest posted price) and as a business strategy (subjects decide whether or not to offer them). Our results show that PMG lead to a clear collusive outcome as markets quickly and fully converge to the collusive prediction if PMG are imposed as a market rule. Whenever subjects are allowed to decide whether to adopt PMG or not we observe that almost all subjects decide to adopt them and prices get very close to the collusive ones.   相似文献

We examine the short-run implications of CO2 trading for power production, prices, emissions, and generator profits in northwest Europe in 2005. Simulation results from a transmission-constrained oligopoly model are compared with theoretical analyses to quantify price increases and windfall profits earned by generators. The analyses indicate that the rates at which CO2 costs are passed through to wholesale prices are affected by market competitiveness, merit order changes, and elasticities of demand and supply. Emissions trading results in large windfall profits, much but not all of which is due to free allocation of allowances. Profits also increase for some generators because their generation mix has low emissions, and so they benefit from electricity price increases. Most emission reductions appear to be due to demand response not generation redispatch.   相似文献

Abstract

A dynamic computational model of a simple commodity economy is examined and a theory of the relationship between commodity values, market prices and the efficient division of social labour is developed. The main conclusions are: (i) the labour value of a commodity is an attractor for its market price; (ii) market prices are error signals that function to allocate the available social labour between sectors of production; and (iii) the tendency of prices to approach labour values is the monetary expression of the tendency of a simple commodity economy to allocate social labour efficiently. The model demonstrates that, in the special case of simple commodity production, Marx's law of value can naturally emerge from multiple local exchanges and operate ‘behind the backs’ of actors solely via money flows that place budget constraints on their local evaluations of commodity prices, which are otherwise subjective and unconstrained.  相似文献

ABSTRACT

The paper pioneers research on high frequency (HF) quoting noise in electronically traded agricultural futures markets. HF quoting – quickly cancelling posted limit orders and replacing them with new ones – emerges as a strategy for liquidity-providing traders. HF quoting can generate noise in price quotes which adds uncertainty to order execution and impairs the informational value of bid and ask prices. It can also lead to the perception that markets cannot be trusted for commercial transactions. Using intraday Best Bid Offer data for 2008–2013 and wavelet-based measures of volatility, we investigate the excess variance and co-movement discrepancies in the bid and ask prices. We find excess HF quoting variance exists. It is the highest at 250-ms scale – 90% higher than the variance implied by a random walk – but declines quickly to 7% at the 32 s scale. But its economic magnitude is negligibly small. Bid and ask price co-movements show a low degree of discrepancy with average correlations at 0.67 at 250 ms and reaching 0.95 at 8 s. All measures indicate that HF quoting noise has declined through the period. Overall, HF quoting has not caused excess variance during the transition to electronic trading in the liquid corn futures market.  相似文献

This paper examines differences in the connectedness between exchange rates and stock prices for companies with different asset currencies on the Hong Kong stock market, and it seeks to explain those differences by proposing a hypothesis on asset-denominated currency difference. Under a framework of investor heterogeneity, we establish a dynamic, discrete theoretical model to analyse the connectedness between exchange rates, the stocks of local Hong Kong companies, the stocks of companies from the mainland and foreign exchange interventions. Using monthly data from January 2000 to August 2018, we adopt the time-varying parameter vector auto-regression (TVP-VAR) model to empirically study the dynamic relationships between exchange rates and the prices of both Hong Kong-based and mainland-based stocks. The results show significant differences in the ways that exchange rates and prices for the two types of stocks are linked. The exchange rates are positively correlated with mainland stocks and negatively correlated with Hong Kong stocks. Moreover, foreign exchange intervention is found to be an effective means for stabilising exchange rates, although such intervention tends to increase stock volatility.

Abstract

The authors investigate the role of mutual fund flows in incorporating market sentiment into asset prices. They show that retail investors adjust their investments among mutual fund categories in response to changes in market sentiment. Consistent with sentiment-induced price pressure through fund flows, they further find that firms favored by mutual funds, such as large-cap, dividend payers, and firms with high institutional ownership are sensitive to market sentiment. The authors construct a pricing factor representing sentiment risk and find that the sentiment factor is significant in standard asset pricing models and robust to various sorting procedure.  相似文献

Abstract:

The goal of this research is to demonstrate a significant importance of state policy of food prices supervision in Israel. The article begins with a detailed discussion of the healthy food basket’s components, based on the Israeli Ministry of Health recommendations. Next, we present the prices of the goods included in the basket, and a calculated estimate of the per capita cost of funding the basket. Based on this cost figure, we assess the economic ability of Israeli households to purchase the basket. The results show that two lowest quintiles would have trouble paying the price of a basic health food basket. Further, it describes the food prices in Israel and its significance, Israel’s food market and the major regulatory tools associated with the food market. In the end, we define the need for short-term and longer-term regulation of food costs, and the necessity of expanding competition in the food market.  相似文献

Abstract

Prior literature finds that short selling is beneficial to the market because it increases liquidity and helps to discipline optimistic market prices. The authors use 2 controlled experiments to examine the potential for an unintended consequence of allowing short selling or easing short selling restrictions. Because prior research identifies short sellers as sophisticated market participants who have the ability to see through accrual earnings management choices, we predict and find that, when reporting is transparent, managers are more likely to use real earnings management relative to accrual earnings management when short selling restrictions are relaxed. This is consistent with the idea that real earnings management activities are more defensible as the result of legitimate operating decisions and are therefore more likely to hold up to scrutiny from short sellers. Overall, the results suggest that regulations that are unrelated to financial reporting can affect how managers respond to the transparency that arises from financial reporting regulations.  相似文献

Abstract

This editorial discusses a number of trends affecting the pricing of generic medicines in Europe. With respect to pricing, recent evidence has emerged that European generic medicine manufacturers face competition from Indian manufacturers; that the price level of generic medicines varies substantially between European countries; and that generic medicine manufacturers engage in competition by discount rather than price competition in France, The Netherlands and the UK. These trends suggest that there may be scope for further reducing the prices of generic medicines in several countries.

In relation to reference pricing, most European countries have incorporated market incentives within reference pricing systems with a view to promoting price competition. The European experience indicates that the generic medicines industry delivers competitive prices under a reference pricing system if demand-side policies are in place that stimulate physicians, pharmacists and patients to use generic medicines.

Finally, caution needs to be exercised when focusing on the drivers of generic medicine pricing as these drivers not only vary between countries, but may also vary within a country. Manufacturers of originator and generic medicines do not take a single pricing approach following patent expiry, but vary their pricing strategy from molecule to molecule.  相似文献

This paper explores the economic implications of different contract durations in markets for on-line (primary and secondary) reserve capacity in Germany with the crucial feature of separate markets for spot energy and reserve capacity provision. The analysis is based on an equilibrium model developed by Just and Weber (Energy Econo 30:3198–3221, 2008) for reserve markets. It reveals the implicit trade-off for the bidders and implicit interdependencies between the reserve and the spot markets. Even if the markets are not explicitly coordinated, they are interrelated through the dispatch decisions of the power plant owners. The paper concludes that the current German reserve market design is inefficient and should be improved. The results clearly show that shorter periods (with resulting lower variations in overall electricity demand) lead to more efficient dispatch and market results. Not only prices in the reserve capacity markets are expected to be lower, but also spot market prices. As these benefits can be partially reaped by owners of large generation portfolios also under longer contract durations, it discriminates against smaller generation companies and can potentially deter market participation. Further, the paper takes a broader perspective and discusses security concerns against shorter contract durations. It is shown that the opportunity costs character of the reserve market implies sufficient incentives for supplying online reserve capacity. The concerns do not appear to be predominant and it should be possible to manage them appropriately.  相似文献

ABSTRACT

‘Crusoe’ and ‘Friday’ signifiers necessarily evoke a world of racialised hierarchies. Economics textbooks are perhaps the sole remaining medium to simply wish away their resulting relations of power. These are the teaching aids that inspire students analytically to think of markets as pristine economic institutions and persuade them politically that they should want to will such institutions into being. Yet they all-too-often rely on the pedagogical device of the so-called Robinson Crusoe Economy, where the main characters from Defoe’s most famous novel are required to instinctively recognise their equality within voluntary contracting agreements so that each can act as the neoclassical homo economicus. In other words, economists’ Crusoe and Friday figures must behave antithetically to what has historically been implied by the ‘Crusoe’ and ‘Friday’ signifiers. But how can this be so, given how commonplace it was when Defoe’s characters were first introduced into economic theory in the 1850s to justify white settler colonialism on the grounds that ‘savage’ societies lacked the capacity to be self-governing? The raced market frame that emerged in practice from this assumption continues to be reproduced uncritically today by Crusoe’s and Friday’s presence in the textbook explanation of the most basic model of market exchange.  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

Abstract

Otto Neurath is notorious amongst economists for his plans for a socialist economy with calculation in kind in place of a market. This paper considers the common criticism of “utopianism” from an immanent point of view. To do so, it will first be established in what Neurath recognized a negative sense of utopianism that was opposed to his own self-confessed “scientific utopianism”. Then it will be considered in what respect, if any, Neurath's stance in the socialist calculation debate can be shown to be objectionably utopian in this sense by the counter-arguments put forward by Ludwig von Mises.  相似文献
