This paper investigates precautionary saving under liquidity constraints in Pakistan using household panel data. In particular, while it estimates Kimball's [Kimball, M.S. Precautionary saving in the small and in the large. Econometrica 1990; 58; 53–73.] prudence parameter based on a framework that is similar to Dynan [Dynan, K.E. How prudent are consumers? Journal of Political Economy 1993; 101; 1104–1113.], this study deviates from the framework by explicitly considering liquidity constraints, as in Zeldes [Zeldes, S.P. Consumption and liquidity constraints: an empirical investigation. Journal of Political Economy 1989; 97; 305–346.]. By doing so, this paper attempts to differentiate the standard precautionary saving caused by uncertainty from that caused by liquidity constraints. Furthermore, endogenous liquidity constraints are used in order to resolve issues of selection biases. We find substantial evidence of the presence of precautionary saving in Pakistan. More specifically, the estimated prudence is significantly higher for liquidity-constrained households as compared with unconstrained ones. The finding suggests that the precautionary saving motives appear stronger when households see that their access to credit markets is limited. 相似文献

This paper investigates how the legal environment in a country influences performance and risk of stock across countries at different developmental stages and of various rules of jurisdiction. Using data of 4916 stocks from 37 countries, our empirical findings confirm that equities in countries with English common law origin have higher risk premiums than those in civil law countries, particularly for countries of the French/Spanish code. The indicators representing high efficiency in law system, low corruption, strong legal protection of investors' rights, and reliable political environment are associated with low risk and high performance. The various elements of legal procedural formalism, however, have differing effects on volatility and return. 相似文献

Does Technological Innovation Really Reduce Marginal Abatement Costs? Some Theory,Algebraic Evidence,and Policy Implications 总被引:1,自引:1,他引:1
The existing literature models innovation in pollution control as a reduction in marginal abatement costs. We show that this
assumption is inappropriate for production process innovations such as fuel switching. Algebraically, we examine the effects
of different innovation types on marginal abatement cost curves, showing that some desirable innovations increase marginal abatement costs. Empirically, we estimate marginal abatement costs for sulfur dioxide by measuring the output distance
function for electric power in Korea. Regression results confirm that production process innovations did raise marginal abatement
costs in this case. One policy implication: economic instruments do not always provide stronger innovation incentives than
command-and-control policies.

Uncovered interest parity (UIP) is estimated for short‐term horizons from one month to 12 months using a large number of cross‐sectional bilateral exchange rates. In contrast to conventional time‐series UIP, cross‐sectional UIP is examined with a single‐equation estimation and panel regression model estimation. The exchange rates analyzed here include a broad spectrum of countries: developed, developing, low‐inflation, and high‐inflation countries. Based on the empirical evidence, there does not appear to be a well‐publicized UIP puzzle for cross‐sectional UIP, and the slope estimates remain largely between zero and one throughout the sample periods, with a few exceptions. Evidence of UIP is more clear for low inflation countries than for high inflation countries. As interest rate maturity becomes longer from one month to 12 months, the UIP relationship becomes weaker. 相似文献

This study constructs a variety of GARCH models with the consideration of the generalized error distribution to analyze the relationship between the cloud cover and stock returns in Taiwan in the whole sample period (1986 to 2007) and in the two sub-sample periods (1986 to 1996 and 1997 to 2007). The data include Taiwan Stock Exchange Capitalization Weighted Stock Index, the primary eight stock sector indices, and the U.S. Dow Jones Industrial Average index to proxy the impact of U.S. stock market on Taiwan's stock market performance. The empirical finding of this study could be used to reconfirm the existence of the so-called sunshine effect. In addition, by comparing the long-run impulse multiplier effects of the cloud cover on the stock return in the two sub-sample periods; this study could examine the transition of the sunshine effect in Taiwan's stock market. The empirical results suggest that cloud cover has a significant negative impact on Taiwan's stock market, especially in the low cloud cover periods. Moreover, the pre-determined distribution of the error term plays an important role on the significance of the sunshine effect. The empirical result shows that most long-run multipliers are negative and the multiplier is more effective in the low cloud cover periods than in the high cloud cover periods. 相似文献

The VoIP (Voice over Internet Protocol) market in Korea is showing rapid growth since domestic carriers initiated the service in 2006. These carriers are now seeking new revenue sources from various convergence services and are increasing investment into VoIP. In particular, local exchange carriers (LECs), formerly reluctant to invest in technologies that would cannibalize their local telephone revenue, have started to invest in VoIP, in recognition of the current convergence of media and the telecommunications industry, as well as in the face of intensifying competition. In this study, we determined that VoIP call rates and landline telephony call rates were the most important factors affecting VoIP call demand, in addition to network externality. We also verified that landline telephony is no longer a supplement to VoIP, but rather, a substitute that has considerable influence on VoIP call demand. Empirical evidence is expected to be considered in policy decision making on current issues in the IT industry, such as access prices or competitiveness assessment. The current empirical analysis on the Korean VoIP industry and the adherence to lessons learned from policy enforcement should provide valuable information to countries seeking to develop their own VoIP industries, as well as to businesses developing new strategies based on the VoIP market. 相似文献

This study presents the nonlinear relationship that exists between financial development and economic growth. This study applies
the flexible nonlinear regression model of Hamilton (Econometrica 69(3):537–573, 2001) because it imposes no specification
restrictions. Two empirical results are obtained. First, an inverted U-shaped relation between banking sector development
and economic growth is identified. Namely, the two variables are positively linked before the turning point, but negatively
linked after it. Second, a positive relationship with asymmetric √-shape between stock market development and economic growth
is found. 相似文献

American students study harder in college than in high school, whereas East Asian students study harder in high school than in college. This article proposes a signaling explanation. Signaling may occur over time both in high school and in college, and societies may differ in the timing of signaling. Students work harder in the signaling stage determined by the society as a whole. A testable implication is that high ability workers in East Asia are more concentrated among a few colleges than their U.S. counterparts. This implication is confirmed by top CEO education profile data in the United States and Korea. 相似文献

We consider a model of the criminal court process, focusing on plea bargaining. A plea bargain provides unequal incentives to go to trial because innocent defendants are more willing to plead not guilty. We show that the court process implements the preferences of the person or group who is most concerned about wrongful conviction. If a prosecutor is more concerned about wrongful conviction than the jury, the prosecutor can shape the defendant pool at trial so that jurors act according to prosecutor’s preferences against judicial mistakes. Our model also connects insights from strategic jury models that usually omit plea bargaining with the actual criminal court process where most cases are resolved through plea bargaining. As an example, we show that the inferiority of the unanimity rule established in Feddersen and Pesendorfer (Am Polit Sci Rev 92(1):23–35, 1998) persists in spite of the addition of plea bargaining. 相似文献
