The European Central Bank (ECB) recently announced its willingness to do whatever is needed to save the euro. This has raised the question whether such a role of the ECB must lead to higher rates of infl ation. Under current recessive macroeconomic conditions in the eurozone, the ECB’s expansionary monetary policy will not lead to higher infl ation. On the contrary, there is a serious danger of defl ation. Higher infl ation would likely occur only if a permanent stabilisation function were assigned to the ECB. Yet historical examples show that mistakes can be made. During the stagnation in Japan, US economists heavily criticised the Bank of Japan’s timid monetary policy response. But in some sense, current Fed policy seems to be a direct copy of that strategy, caused by uncertainty about the proper communication channel. An infl ation tax could help to bring down the mounting public debt in the wake of the fi nancial crisis, but higher wealth taxes have more transparent distributional effects. 相似文献

The presence of implicit observation cues, such as picture of eyes, has been shown to increase generosity in dictator games, and cooperative behavior in field settings. I combine these approaches, by testing if a picture of watching eyes affects unconditional giving in a natural environment, where the recipient is a charity organization. Taken together, this study reduces the influence of three potential confounding factors in previous experiments: (i) experimenter demand effects, (ii) that the facial cue reminds subjects of a human counterpart, and (iii) a social multiplier effect. Specifically, the paper reports results from an experiment, conducted in a Swedish supermarket chain, where customers face a naturally occurring decision problem. People who recycle cans and bottles have to choose whether to keep the recycled amount or donate it to a charity organization. By posting a picture of human eyes on recycling machines, I am able to test whether this causes an increase in donations to the charity. Based on a sample covering a 12-day period, 38 stores and 16775 individual choices, I find no general effect. However, when controlling for store and day fixed effects, and using a proxy for store attendance, the picture of eyes increased donated amount by 30 percent during days when relatively few other people visited the store. This result gives further support to the conclusion that subtle social cues can invoke reputation concerns in humans, although the relatively small effect suggests that previous estimates could be biased upward, or at least that the influence of observational cues is context dependent. 相似文献

As the information relative to endowments, costs and preferences is dispersed among many agents, the quality of resource allocation
depends on the ability of markets to communicate information inside the economic system. Because information is transferred
through negotiation and transaction behaviors, the network of trading relations defines the channels through which it flows.
In the present study, we use new computational tools to analyze the performance of two wholesale trade institutions widely
used around the world: network trading and marketplace trading. Whilst network trading and marketplace trading disseminate
far fewer bits of information than a perfectly transparent benchmark market, they often manage to generate an allocation of
resources that is almost as good. In many cases, network trading proves more effective than marketplace trading (contrary
to a common preconception). This surprising performance of network trading is linked to a form of indirect arbitrage induced
by connections between networks. Implications for market design and public policy making are presented, along with prospects
for further research. 相似文献

We test for the existence of market discipline by shareholders of banks with a wide range of ownership structures. Discipline by shareholders manifests itself through monitoring banks’ level of risk as well as through influencing banks’ management actions. We find that shareholders utilize the relation between stock returns and different types of risk measures to monitor risky banks. Shareholders partially influence bank management by responding to decreasing stock returns with a demand to improve loan quality. Moreover, the influence on management in small banks is more pronounced compared to large banks. 相似文献

The development in the working of markets has been an important topic in economic history for decades. The volatility of market
prices is often used as an indicator of market efficiency in the broadest sense. Yet, the way in which volatility is estimated
often makes it difficult to compare price volatility across regions or over time for two reasons. First, if prices are non-stationary,
the variance is inflated. Second, the variance of commodity prices contains information on a number of region- and time-specific
factors that are not related to market efficiency. Hence, the popular coefficient of variation and related indicators are
not adequate measures of the efficiency of markets and are incomparable across regions. As a solution, we suggest using a
conditional heteroscedasticity model to estimate the residual (conditional) variance of commodity prices. This measure reflects
how markets react to unexpected events and can therefore be seen as a measure of market efficiency. Using this approach on
grain prices from the Early Modern Pisa, Paris, Vienna, and Japan, we find that the residual price volatility had declined
(and market efficiency increased) in the European markets in the late sixteenth century while it remained stable in Japan. 相似文献

We analyze the role of the new goods margin in the Baltic countries’ exports and imports growth during the 1995–2008 period. Using the methodology developed in Kehoe and Ruhl (2013), we define the set of least-traded goods as those that account for the lowest 10% of total exports and imports in 1995, and then trace its growth in several markets including the Baltics’ main trade partners, the European Union and Russia. We find that, on average, by 2008 least-traded goods accounted for nearly 50% of total Baltic exports to their main trade partners. Moreover, we find that increases in the share of least-traded exports coincided with the timing of the trade liberalization reforms implemented by the Baltic countries. Least-traded imports also grew at robust rates, but their growth was lower than that of exports, accounting for slightly less than a quarter of total imports, that is, about half of the exports value. Moreover, we find that the shares of least-traded imports from the EU 15 and from Russia started diverging around the time the Baltic countries joined the EU, with the EU 15 share increasing and the Russian one declining. We also find that the Baltics’ share of least-traded exports outpaced that of other economies in Central and Eastern Europe. Finally, exports of new goods from the Baltic countries suffered noticeably during the Global Financial Crisis. After the crisis ended, the restart in new goods exports growth displayed mixed patterns. 相似文献

Nonlinear models with panel data 总被引:1,自引:0,他引:1
Panel data play an important role in empirical economics. With panel data one can answer questions about microeconomic dynamic behavior that could not be answered with cross sectional data. Panel data techniques are also useful for analyzing cross sectional data with grouping. This paper discusses some issues related to specification and estimation of nonlinear models using panel data.JEL Classification:

Gross stocks of foreign assets have increased rapidly relative to national outputs since 1990, and the short-run capital gains
and losses on those assets can amount to significant fractions of GDP. These fluctuations in asset values render the national
income and product account measure of the current account balance increasingly inadequate as a summary of the change in a
country's net foreign assets. Nonetheless, unusually large current account imbalances, especially deficits, should remain
high on policymakers' list of concerns, even, for the richer and less credit-constrained countries. Extreme imbalances signal
the need for large and perhaps abrupt real exchange rate changes in the future, changes that might have undesired political
and financial consequences given the incompleteness of domestic and international asset markets. Furthermore, of the two sources
of the change in net foreign assets—the current account and the capital gain on the net foreign asset position—the former
is better understood and more amenable to policy influence. Systematic government attempts to manipulate international asset
values in order to change the net foreign asset position could have a destabilizing effect on market expectations. JEL no.
