How resilient and countercyclical were emerging economies during the global financial crisis?

By studying the cross-country incidence of the 2008–2009 global financial crisis, we document a structural break in the way emerging economies responded to the global shock. Contrary to popular perceptions, emerging economies suffered growth collapses (relative to the pre-crisis levels) comparable to those experienced by developed economies, even when they continued growing. Afterwards, most economies returned to their pre-crisis growth rates. Although emerging economies were not able to avoid the collapse originated in the U.S. and then transmitted across countries, they were more resilient during the global crisis than during past crises. Namely, they resumed their higher growth rates earlier and converged more quickly to their pre-crisis growth trend. Moreover, breaking with the past, emerging economies did not fall more than developed economies during the global crisis and were able to conduct countercyclical policies, thus becoming more similar to developed economies.     

Food Safety and Adverse Selection in Rural Maize Markets

Without enforced standards or reliable third-party verification, food safety threats such as pesticide residues and aflatoxin contamination are generally unobservable or only partially observable to both buyers and sellers, especially of staple foods in rural maize markets in sub-Saharan Africa. As a result, sellers have more information about food quality than do buyers. Such information asymmetries can impede market development and undermine human health. We study farm household behaviour in the context of imperfect food safety information. We pool observations obtained from 707 food storage containers maintained by 309 farm households in Benin, surveyed following the maize harvests of 2011/2012 and 2013/2014. Our results indicate that when a household perceives a food safety risk associated with application of insecticides, on average it is 33 percentage points less likely to apply insecticides to maize it intends to consume than it is to maize it intends to sell. These individuals are also more likely to sell maize than households without food safety concerns. Results highlight the potential value of improved storage technologies and quality control to promote market transactions and reduce hidden health risks.     

A portfolio approach to the optimal mix of funded and unfunded pensions

ABSTRACT

In this paper, we address the optimal funding of pensions by means of portfolio choice approach. Considering the unfunded (Paygo) pension system as a ‘quasi-asset’ with hedging and diversification properties, we derive the optimal portfolio mix of funded and Paygo systems within a mean variance and Bell linear exponential models. Our analysis involves both analytical computations and empirical estimations of optimal values using real long-term data for equity, bonds and the Paygo asset for several OECD countries and several time periods covering the time span 1897–2016. We find that in most cases a mix of both systems is desirable with a larger magnitude of Paygo system in the case of the Bell framework as we capture attitudes towards asymmetry and tail risks that are typical to equity markets.     

An Explicit Mapping of Currency Target Zone Models to Option Prices*

Currency target zones have been under scrutiny for the past three decades, which led to the development of two broad classes of quantitative models: Phenomenological ones that explicitly take into consideration the market's perception of the bounded exchange rate, and more mechanical ones that rely on put and call options. Until now, the two models have only been compared qualitatively. Here, we derive, for the first time, a quantitative link between these two approaches. Specifically, we show how the former approach has to be generalized in order to recover the second one. This mapping lets us relate the phenomenological parameter of the first approach to economically well‐known quantities.     

Trade and the location of industries: Some new results

We study a two-country two-sector model with free entry and monopolistic competition where both industries use labour to produce differentiated goods. The two countries are identical except for size. Labour is freely mobile across industries but it cannot move internationally. Transport costs affect both industries. The location of industries and the pattern of trade are the results of the interaction of two effects: the home market effect and the wage differential effect. The main results are: (i) if the two countries are sufficiently close in size and demand elasticities differ across industries (transport costs being equal), a continuous fall in transport costs from a prohibitive level to zero is associated with a reversal in the pattern of trade at some intermediate level. For large transport costs, the large country is a net exporter of the more differentiated good. For lower transport costs, the large country becomes a net exporter of the less differentiated good; (ii) if the two countries are very different in size and demand elasticities differ across industries (transport costs being equal), the larger country is always a net exporter of the less differentiated good.     

An Econometric Study of Quits Rate Trends in the United States since the Great Recession: Cyclical Movement or Structural Change?

This paper attempts to identify the possible reasons behind a drop of the quits rate in the period since the Great Recession. (As defined by the U.S. Bureau of Labor Statistics, the quits rate is the number of quits during the entire month as a percent of total employment.) The paper examines several essential questions on the quits rate using econometric models and analysis: What are the crucial determinants that explain the movements in the quits rate? Is the postrecession stagnation of the quits rate a result of current cyclical macroeconomic conditions, or does it reflect a structural change? As far as we know, no recent research has attempted to model this indicator to answer these questions. Quits rate data have been systematically collected by the Bureau of Labor Statistics through the Job Opening and Labor Turnover Survey (JOLTS) only since the end of year 2000. By dividing our data set into 12 industrial categories and four regions, we are able to come up with empirical models to explain quits rate behavior over a consecutive time span and also across industries and regions. After developing our model, we are then able to examine if there is evidence of structural change using several methods.     

Regulating a manager whose empire-building preferences are private information

We obtain the optimal contract for the government (principal) to regulate a manager (agent) who has a taste for empire-building that is his/her private information. This taste for empire-building is modeled as a utility premium that is proportional to the difference between the contracted output and a reference output. We find that output is distorted upward when the manager’s taste for running large firms is weak, downward when it is strong, and equals a reference output when it is intermediate (in this case, the participation constraint is binding). We also obtain an endogenous reference output (equal to the expected output, which depends on the reference output), and find that the response of output to cost is null in the short-run (in which the reference output is fixed), whenever the manager’s type is in the intermediate range, and negative in the long-run (after the adjustment of the reference output to equal expected output).     

董事会的战略角色

正如果董事会能够清晰地定义自己在公司内的战略功能,董事会内部、董事会与高管之间的争议将大大减少光怪陆离的世界,商业模式快速遭遇颠覆,新的竞争者层出不穷,为了生存发展,公司高层比任何时候都更加需要战略思维。不幸的是,董事会似乎仍然不知道应该如何在公司里发挥战略性作用。一种极端情况是,董事会就是CEO决策程序里一个橡皮图章;     

Conflicting attitudes and scepticism towards online shopping: the role of experience

Researchers typically study how levels of risk perception about online shopping affect whether and how consumers use the channel to buy products. In this paper, we propose to study how different types of attitudes towards online shopping are formed when consumers consider both the benefit and the risk of using the Internet to do their shopping. We consider the possibility that general types of attitudes are formed when consumers' perception of the risk and the benefit of using online shopping conflict. We pay particular attention to the concept of online shopping scepticism where consumers may fully realize the benefit of using the Internet to do their shopping, but also express a certain level of concern about the risk of using that channel. In the risk literature, researchers have shown that experience and increased exposure to a particular technology usually involves the accumulation of more and better knowledge that in turn may lead to a reduction in the perception of the risks involved. In this research, we also explore the role of experience in the context of consumers' intention to use online shopping. More specifically, we postulate that online shopping experience has a direct effect as well as an indirect effect on the intention to use online shopping. Experience with online shopping directly increases the consumer's intention to use the Internet to buy products but it also reduces the degree of scepticism and risk aversion, and that in turn, also increases the intention to use online shopping.
