We select a small set of recommendations that lie in the upper and lower tail of the empirical distribution of divergences between a recommendation, and the consensus over the window (−30, −1) days prior to that recommendation. We classify these extremely divergent recommendations as bold, and then subdivide them into informative bold recommendations that lead other analysts (leading-bold) and those that are ignored by other analysts (contra-bold) based on the consensus change in the 30 days after the announcement. We focus on the information conveyed to the market by these bold, leading-bold, and contra-bold recommendations through their effects on cumulative abnormal returns (CAR). We find that bold recommendations are not anticipated by market participants (CARs are negative before a bold buy and positive before a bold sell). The next finding is that the market responds strongly to both leading and contra-bold recommendations over the (0, +4)-day window and that these reactions are stronger than that to nonbold recommendations. In contrast, over the longer (0, +30)-day window, leading-bold recommendations earn additional returns whereas contra-bold ones reverse significantly due to lack of confirmation. The overall pattern is one of rational market reaction both in the short and long windows. We support the rationality of the market reaction by showing that the percentage of leading-bold recommendations exceeds that of contra-bold recommendations, and that these two types of recommendations cannot be separated using observable analyst characteristics such as experience or brokerage size. 相似文献

Zusammenfassung Die Theorie der Lohnunterschiede, des induzierten tech-nischen Fortschritts und die reine Theorie des internationalen Handels.
— In der Literatur über die Theorie der Lohnunterschiede und des internationalen Handels wird gew?hnlich angenommen, die Lohnunterschiede
seien exogen und die Ausgangs-lage sei ein Gleichgewicht. Der vorliegende Aufsatz geht abweichend davon von einem Ungleichgewichtszustand
aus. Es wird ein Modell entwickelt, in dem technischer Fortschritt als Folge intersektoraler Lohnunterschiede entsteht (unter
der Annahme einer Untergrenze für die Lohns?tze, die durch Subsistenzüberlegungen bestimmt wird). Aus der Untersuchung ergibt
sich folgendes: (1) Eine Volkswirtschaft, die durch Lohnunterschiede gekennzeichnet ist, kann sich in eine Volkswirtschaft
mit Subsistenz-L?hnen verwandeln. In diesem Fall gibt es automatische Kr?fte, die das System von einem Typ verzerrender Rahmenbedingungen
(Lohnunterschiede) zu einem anderen Typ verzerrender Rahmenbedingungen (Subsistenz-L?hne) überleiten. (2) Eine Volkswirtschaft,
die durch Lohnunterschiede gekennzeichnet ist, kann eine optimale L?sung infolge des Wirkens zweier Arten von technischem
Fortschritt erreichen, n?mlich (a) durch den technischen Fortschritt, der durch intersektorale Lohnunterschiede hervorgerufen
wird und (b) durch den technischen Fortschritt vom Kennedy-Typ.
Die Literatur über Lohnunterschiede und Handel war haupts?chlich damit besch?ftigt, die Folgen eines exogen bestimmten Lohnes,
der keine Beziehungen zu den Parametern des Modells hat, zu untersuchen, und hat dabei die Prüfung der Mechanismen vernachl?ssigt,
die imstande sein k?nnen, die Lohnunterschiede zu beseitigen. Dieser Aufsatz ist ein kleiner Beitrag dazu, diese Lücke im
Schrifttum auszufüllen.
Résumé La théorie des différentiels salariaux, le progrès technique induit et la théorie pure du commerce international. — Dans la littérature sur la théorie des différentiels salariaux et le commerce international, on généralement regarde le différentiel salarial comme être exogène et la position initiale comme être une position d’équilibre. Ce papier se sépare de cette pratique générale et regarde la situation initiale comme être une position de diséquilibre. Nous établons un modèle dans lequel le progrès technique entre comme conséquence d’un différentiel salarial intersectoriel (en supposant l’existence d’une borne plus basse des taux salariaux à cause de la considération de subsistence). Les propositions suivantes sont déri-vées de l’investigation, (1) Une économie caractérisée par un différentiel salarial peut transformer elle-même dans une économie de salaire minimum de subsistence. En conséquence il y a des forces automatiques menant le système d’un type de cadre distors (différentiels salariaux) à un autre type de cadre distors (salaire minimum de subsistence). (2) Une économie caractérisée par un différentiel salarial peut arriver à une solution de ?first best? via l’opération des deux types du progrès technique, viz. (a) le progrès technique induit par le différentiel salarial intersectoriel et (b) le type du progrès technique de Kennedy. La littérature sur les différentiels salariaux et le commerce extérieur a princi-palement exploré les conséquences d’un taux salarial fixé exogènement qui n’interagit pas avec les paramètres du modèle et c’est pourquoi a négligé l’étude des mécanismes automatiques qui peuvent éliminer le différentiel salarial. Ce papier est une contri-bution mineure de remplir la lacune dans la littérature sur les différentiels salariaux et le commerce extérieur.
Resumen La teoría de los salarios diferenciales, progreso técnico inducido y la teoría pura del comercio internacional. — En la literatura sobre la teoría de los salarios diferenciales y el comercio international, la diferencia salarial se considera generalmente como exógena y la posición inicial como una posición de equilibrio. El presente artículo se aleja de esta práctica general y considera la situación inicial como una posición de desequilibrio. Se construye un modelo en que el progreso técnico se produce como una consecuencia del salario difenrencial intersectorial (asumiendo la existencia de un límite aún inferior para las tasas salariales determina-das por la consideratión de subsistencia). Las proposiciones siguientes emergen de la investigación. (1) Una economía caracterizada por una diferencia salarial puede transformarse en una economía de salarios mínimos de subsistencia. De tal manera existen fuerzas automáticas que llevan el sistema de un tipo de marco distorsionador (salarios diferenciales) a otro tipo de marco distorsionador (salarios minimos de subsistencia). (2) Una economía caracterizada por salarios diferenciales puede alcanzar una solución first best via la operación de dos tipos de progresos técnicos, (a) progreso técnico inducido por el diferencial salarial intersectorial y (b) el tipo Kennedy de progreso técnico. La literatura sobre salarios diferenciales y comercio se ha preocupado en su mayor parte de la exploración de las consecuencias de una tasa salarial fijada exó-genamente que no interactúa con los parámetros del modelo, no habiéndole dado la debida importancia al estudio de mecanismos automáticos que pueden ser capaces de remover las diferencias salariales. Este artículo es una contribución menor hacia el relleno de la laguna en la literatura sobre salarios diferenciales y comercio.相似文献

Illegal Migration, Border Enforcement, and Growth 总被引:2,自引:0,他引:2
This paper analyzes the economic consequences of illegal migrants in the context of a model of trade and growth. In the model, capital and domestic labor are mobile sectors while illegal migrants are sector-specific. These assumptions give rise to a production possibility curve (with migrants) that lies partially inside the zero migration production possibility frontier. It is this feature of the model which generates ambiguous results regarding the relation betweendomestic welfare, illegal migrants, and enforcement. The steady-state growth path with migrants may lie above or below the balanced growth path without migrants. 相似文献

This study evaluates the economics of the choice of form of payout initiation mechanism adopted by IPO firms. Our results suggest that IPO firms demonstrate a preference for repurchases over dividends as the specific form of payout initiation mechanism. We however, find that while the market views post-IPO payout initiations favorably, it is indifferent to the specific form of payout mechanism adopted. Further, we find that dividends and repurchases represent distinct payout mechanisms adopted by IPO firms with fundamentally different characteristics and motivation to initiate payouts during the post-IPO phase. Our results suggest that while dividend initiations are primarily driven by life cycle and catering theory considerations, signaling theory provides the more likely explanation for payout initiations through share repurchases. 相似文献

The Effectiveness and Targeting of Television Advertising 总被引:1,自引:0,他引:1
Television networks spend about 16% of their revenues on tune-ins, which are previews or advertisements for their own shows. In this paper, we examine two questions. First, what is the informational content in advertising? Second, is this level of expenditures consistent with profit maximization? To answer these questions, we use a new and unique micro-level panel dataset on the television viewing decisions of a large sample of individuals, matched with data on show tune-in advertisements. The difference in effectiveness of advertisements between “regular” shows (about which viewers are assumed to have substantial information a priori) and “specials” (about which they have very little) reveals the value of information in advertisements and the different roles that information can play. The number of exposures for each individual is likely to be correlated with their preferences, since networks target their audiences. We address this endogeneity problem by controlling for observed, and integrating the unobserved, characteristics of individuals, and find that the estimated effects of tune-ins are still large. Finally, we find that actual expenditures on tune-ins closely match the predicted optimal levels of spending. 相似文献

This article examines the consequences of changes in final and intermediate good tariffs on structural adjustment, urban unemployment, and the real exchange rate in the presence of a free trade zone (FTZ) and foreign capital in the host country. The location of the FTZ and the disaggregation of the economy allows us to examine the consequences of a tariff change on regional incomes. It is shown that as a consequence of a tariff change the urban and rural incomes need not necessarily move in the same direction (hence the potential for rural and urban conflict in policy making). It is also shown that an increase in the tariff on an immediate good may result in both export promotion and an increase in welfare. Such expansion is a nonconventional result, since raising barriers to trade normally leads to a contradiction in the volume of the trade. The interconnection between the real exchange rate and intermediate good tariff is also explored in this article. It is shown that a policy of imposing tariffs on these goods may result in the appreciation of the real exchange rate. 相似文献

A major problem in many developing countries is the degradation of commons. This degradation has occurred on account of the lack of fulfilment of the basic needs of the poor, free riding and ill–defined property rights. As these goods are essential for the survival of these people, they have to access these items from commons. This results in regular raids to common land for resources and also to private houses (for example, in New Delhi) which are not guarded for water. A variant of the agricultural household model is used to analyse the above problem. Several propositions are established and it is demonstrated that degradation can occur at both a low and high price of basic needs. This result has important policy implications as it demonstrates that land or common degradation cannot be solved by just using the price system. Properly defined property rights and provision of basic goods in kind may resolve the problem of degradation of commons. 相似文献

Agricultural policy in developing countries is strongly shaped by views about speculation in the foodgrain markets. The central issue is whether speculative expectations are rational. Yet, data availability and the absence of futures markets rarely permits a direct examination of this hypothesis. However, the government intervenes in the Indian wheat market in a manner that allows speculative expectations to be inferred from government purchase of grain. The application of standard tests of rational expectations is complicated by measurement errors. Results show systematic biases in forecasting errors of a form that would not be sustainable in the presence of a futures market. 相似文献

This paper examines the effects of pollution taxes on welfare and environment for a small open economy. In the presence of tourism, pollution taxes provide a double dividend of less pollution and improvements in the tourism terms of trade. The optimal pollution taxes are derived under exogenous and endogenous tourism, and they can be greater or less than the marginal damage of pollution perceived by the domestic residents. Numerical simulations show that the optimal tax rate is larger under exogenous tourism. 相似文献
