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 no-trade result of Milgrom and Stokey, J Econ Theory 26:17–27 (1982), states that if rational traders begin with an ex-ante Pareto optimal allocation then the arrival of information cannot generate trade. This paper allows traders to trade before and after the arrival of information. If there are enough securities to hedge against all payoff relevant risk, then the preinformation-arrival allocation is Pareto optimal and information arrival has no effect. This no-retrade result is the competitive analog of the no-trade result of (1982). However, information generically generates trade when markets are state-contingent incomplete.We thank seminar participants at Cambridge, Carnegie Mellon,Cornell, Essex, London, Maastricht, USC, and York and participants at the 2003 SITE, the 2003 SAET and the Fall 2002 Cornell–Penn State Macro Conference.

The daily consumer price index (CPI) produced by the Billion Prices Project (BPP CPI) offers a glimpse of the direction taken by consumer price inflation in real time. This is in contrast to the official U.S. CPI, which is compiled monthly and released with an average of a three-week delay following the end of the reference month. A recent body of research contended that the movements of online prices are representative of those of offline retail prices, making the BPP CPI a natural candidate for accurately improving the timeliness of the official CPI. We assess the predictive content of the BPP CPI using a variety of MIDAS models that accommodate data sampled at different frequencies. These models generate estimates that remain robust to the variety of time periods considered and, by the standard of the existing literature, contribute to a significant upgrade in the forecast accuracy of official consumer price inflation figures. The paper then sketches the broad implications of BPP CPI for the consumer price statistics maintained by national statistics offices and discusses how the proposed improvement in the timeliness of the official CPI fits in this perspective.  相似文献

The paper shows that the Canadian System of National Accounts includes exhaustible resources but treats them as if they were produced goods. Thus, the claim that conventional accounts ignore the contribution of exhaustible natural resources is partly true. To fully account for exhaustible resources, we present an alternative national accounting framework that incorporates natural resource flows and stocks. The framework modifies the measure of the net domestic product by a factor that differs from the Hartwick-Solow-Weitzman rule and leads to different estimates of GDP, national wealth, and productivity growth. An application to the Canadian oil and gas industry shows order-of-magnitude effects.  相似文献

ABSTRACT

It is well documented that there has been a relationship between stock markets and unconventional monetary policies. However, most research concentrates on developed economies and analyzes the effects of shocks from such polices on stock prices. This paper is different from this research in that we investigate the impact of surprises from the Fed’s and the ECB’s announcements on the stock returns and volatility in Gulf Cooperation Council (GCC) countries using GARCH models. We find that a positive surprise associated with a fall in the U.S. Treasury yield causes an increase in ADX returns. We show significant effects of the ECB’s shocks on price returns. In particular, announcement that induces a decline in yield spreads in Italian sovereign bonds leads to higher stock prices. We also document a significant impact of surprises both by the Fed and ECB on volatility. However, the estimates are mixed. We note that volatility went down in response to the ECB’s policies, while they increased after the Fed’s asset purchases. Finally, when we distinguish surprises by their sign, the GJR-GARCH model estimates indicate that the effect on the volatility which is, perhaps surprisingly, symmetric for both types of news.  相似文献

The objective of this paper is to determine the managerial governance characteristics related to financial distress companies. The boards failed to accomplish their monitoring duties, which seemed to be one of the main reasons behind the actual financial distress and bankruptcy that swept the companies across the planet. Through the analysis of a sample of 178 Lebanese non listed and owned family firms, the results showed that the boards (that have a higher proportion of outside directors) are less inclined to face a financial distress than the boards with a lower proportion. Besides, a different conclusion proves that the board’s size and financial distress are directly linked. The paper highlights the extent to which financial distress is associated with corporate governance from a Euro Mediterranean country. It would be a source of education to Lebanese investors who excessively go for short-term returns and of help for regulatory authorities in the framework of making policies on corporate governance reformation.  相似文献

Although economic classification is not part of the Ruggles's prodigious contributions to the System of National Accounts, it is certainly meant to help achieve the integration and linking of macrodata with microdata. Unfortunately, economic classification is a component of the statistical infrastructure that often remains unquestioned by the existing industrial organization literature. This paper fills this gap using the banking business under the 1997 North American Industry Classification System (NAICS) as an example. More specifically, the paper ascertains the extent to which NAICS succeeds at combining the various activities performed by Canadian banks into homogeneous industries. Assuming that producing units within the same industry should display more similar cost structure than those in less similar industries, we find that NAICS—at least for the banking sector—is successful at identifying and grouping producing units into homogeneous economic activities. This result is particularly helpful for empirical research that relies on microdata to draw inferences on the structures, conduct and economic performance of the banking sector as whole.  相似文献

This article statistically tests the option theory of irreversible investment. Using contingent claims valuation, we derive the value of options to invest in capacity, where the projects are endogenous to the economic circumstances prevailing at the investment date. We then test whether decisions made by Canadian copper mines are compatible with the trigger price implied by the theory. Our model explains investment size and timing satisfactorily from a statistical and an economic point of view; simulations with a mean-reverting process suggest that the results do not depend crucially on the assumption that price follows a geometric Brownian motion.  相似文献

From 1970 to 2010, sub-Saharan African’s (SSA) labour productivity hovered at around 6% of the US level. This lacklustre performance, which remained stubbornly low despite the SSA’s growth spurt that started in the mid-1990s, masks a great deal of variations across sectors and countries. Using a structural decomposition, we examine, for a representative sample of SSA countries, the sectoral sources that hold back their convergence to the US frontier. Our results suggest the presence of strong – and possibly long-lasting – headwinds that have wiped out the favourable effects of substantial, yet circumstantial, tailwinds. Headwinds, quantified by the unfavourable within- and reallocation-effects, are indicative of significant capital-deepening and technology gaps, both of which are extremely hard to bridge. The tailwinds, represented by favourable between-effects, result from the convergence of the SSA labour force to sectors where some US sectors have seen a slowdown of their productivity relative to that of the whole economy – a development unrelated to the fundamentals underlying the SSA economy. Although few exceptions emerged out of this general pattern, these results are indicative of a bleak outlook for the SSA economic performance at least in the medium run.  相似文献

We examine the relation among average returns, market beta, firm size, and book-to-market value for Canadian stocks during 1975–92. We document a negative relation between average return and the market capitalization of firms, but find no relation between average return and market beta. While the small firm effect is significant during a period of reduced capital gains tax, it is noticeably lower than during the period leading up to the change. We find that average returns are positively related to book-to-market value especially during the period of lower capital gains tax.  相似文献
