The paper studies the effects of mortgage choices between fixed‐rate mortgages (FRMs) and adjustable‐rate mortgages (ARMs) on labor market efficiency. FRMs provide insurance for risk‐averse borrowers in the sense that they pay the same rate over time and are not subject to uncertain spot market rates. FRMs, however, discourage borrowers from moving to other regions despite better employment opportunities, as they terminate the FRM contracts in order to move and their new loan interests may be higher. As FRM‐borrowers do not move to other regions due to the interest lock‐ins, entrepreneurs in other regions lose the potential surpluses from productive matches that would have occurred between borrowers‐workers and entrepreneurs. Borrowers ignore this negative externality they impose on the entrepreneurs when choosing their mortgages, and too many borrowers choose FRMs relative to the efficient level. If FRMs are eliminated and ARM‐insurance (that protects ARM‐borrowers against uncertain adjustable interest rates) is created, it will improve efficiency. The paper also assesses quantitatively the welfare effects of eliminating FRMs and providing ARM‐insurance.  相似文献

Between 2000 and 2003 a series of disclosure and analyst regulations curbing abusive financial reporting and analyst behavior were enacted to strengthen the information environment of U.S. capital markets. We investigate whether these regulations reduced security mispricing and increased stock market efficiency. After the regulations, we find a significant reduction in short‐term stock price continuation following analyst forecast revisions and earnings announcements. The effect was more pronounced among higher information uncertainty firms, where we expect security valuation to be most sensitive to regulation. Analyst forecast accuracy also improved in these firms, consistent with reduced mispricing being due to an improved corporate information environment following the regulations. Our findings are robust to controls for time trends, trading activity, the financial crisis, analyst coverage, delistings, and changes in information uncertainty proxies. We find no concurrent effect among European firms and a regression discontinuity design supports our identification of a regulatory effect.  相似文献

This note re‐examines the previous results on durable goods monopolists under the time inconsistency problem that the firm tends to make its goods less compatible as a “planned obsolescence” strategy in the presence of network effects. We find that the possibility of the commitment to forward compatibility is profitable to the monopolist, depending upon the degree of technological progress and network effects. Therefore, contractual commitments that are frequently feasible and observed in real‐world markets make the society better off.  相似文献

This paper re‐examines the stationarity of inflation rates in 19 Organisation for Economic Cooperation and Development countries with the use of cross‐sectional information. We employ the panel unit‐root tests that allow for cross‐sectional dependency and the covariate point optimal test. These tests have high power in common due to the exploitation of cross‐sectional information, and they can assist mutually to draw a concrete conclusion on inflation dynamics for all series in the panel. Our empirical results show that allowing for cross‐sectional dependency rejects the null hypothesis that all series in the panel have a unit root, implying that there is at least one stationary series in the panel. With the help of the results of the covariate test, we can distinguish the panel into a group of stationary and a group of non‐stationary series. For robustness, the two groups of series are re‐confirmed by the panel tests. Our results reveal evidence of mean reversion in inflation for 15 of 19 countries, which is significantly stronger as compared to that obtained by the state‐of‐the‐art univariate unit‐root tests.  相似文献

Abstract. Option market activity increases by more than 10 percent in the four days before quarterly earnings announcements. We show that the direction of this preannouncement trading foreshadows subsequent earnings news. Specifically, we find option traders initiate a greater proportion of long (short) positions immediately before “good” (“bad”) earnings news. Midquote returns to active-side option trades are positive during nonannouncement periods and are significantly higher immediately prior to earnings announcements. Bid-ask spreads for options widen during the announcement period, but traders do not gravitate toward high delta contracts. Collectively, the evidence shows option traders participate generally in price discovery (the incorporation of private information in price), and more specifically in the dissemination of earnings news.  相似文献

Income is indeed a will-o'-the-wisp. One of its modem founding fathers was Irving Fisher, who emphasized the psychic experience of consumption. This paper discusses some aspects of Fisher's contribution to the continuipg debate on the elusive concept of income.
Le revenu est un vrai feu follet. Un de ses fondateurs actuels fut Irving Fisher qui fit valoir l'aspect psychique de la consommation. Ce papier examine certains aspects de l'intervention de Fisher dans les débats incessants dirigés sur I'insaisissable concept du revenu.
Das Ertragskonzept ist allerdings ein Irrlicht. Einer seiner modernen Stamniväter war Irving Fisher, der die pschische Erfahrung yon Verbrauch zum Ausdruck brachte. Diese Abhandlung besprict einige Aspekte des Fisher-Beitrages zur fortdauernden Debatte uber das schwer erfassbare Ertragskonzept.  相似文献
