Risk‐Off Episodes and Swiss Franc Appreciation: The Role of Capital Flows

During episodes of increased global risk aversion, or risk‐off episodes, safe haven currencies such as the Swiss franc tend to appreciate. The immediate impact of a risk‐off shock is an increase in net private inflows to Switzerland, mostly driven by a reduction in Swiss residents’ net purchases of foreign debt securities and reduced foreign exposure by Swiss banks. Given that the bulk of capital movements related to risk‐off episodes is driven by decisions of Swiss residents, capital flow management policies that discriminate based on the residency of the investor (capital controls) are not likely to be effective at reducing the impact of risk‐off episodes. However, prudential policies that limit leveraging or foreign exposure by Swiss banks may diminish the volatility of capital flows during risk‐off episodes.     

Impact of International Remittances on Schooling in the Philippines: Does the Relationship to the Household Head Matter?

We study the impact of international remittances on schooling in the Philippines, taking into account the school‐age individual's relationship to the household head. This consideration is important because employment opportunities abroad may be taken at the expense of the quality of child rearing. Our estimation results indicate that there are, indeed, significant negative guardian effects on school attendance and education expenditures when children with overseas parents are looked after by a relative other than a parent or grandparent. However, these negative effects tend to be outweighed by the positive impact of remittance flows from overseas.     

The Fundamental Theorem of Asset Pricing under Proportional Transaction Costs in Finite Discrete Time

We prove a version of the Fundamental Theorem of Asset Pricing, which applies to Kabanov's modeling of foreign exchange markets under transaction costs. The financial market is described by a   d × d   matrix-valued stochastic process  (Π _t ) ^T _{t =0}  specifying the mutual bid and ask prices between d assets. We introduce the notion of "robust no arbitrage," which is a version of the no-arbitrage concept, robust with respect to small changes of the bid-ask spreads of  (Π _t ) ^T _{t =0}  . The main theorem states that the bid-ask process  (Π _t ) ^T _{t =0}  satisfies the robust no-arbitrage condition iff it admits a strictly consistent pricing system. This result extends the theorems of Harrison-Pliska and Kabanov-Stricker pertaining to the case of finite Ω, as well as the theorem of Dalang, Morton, and Willinger and Kabanov, Rásonyi, and Stricker, pertaining to the case of general Ω. An example of a  5 × 5  -dimensional process  (Π _t )² _{t =0}  shows that, in this theorem, the robust no-arbitrage condition cannot be replaced by the so-called strict no-arbitrage condition, thus answering negatively a question raised by Kabanov, Rásonyi, and Stricker.     

Doing Unto Others: The Reciprocity of Helping Behavior in Organizations

Reciprocity is a fundamental aspect of social life, and a phenomenon studied from a wide variety of philosophical, theological, and social scientific perspectives. In this study, we use social exchange theory to investigate why employees help other employees. We hypothesize, based on the norm of reciprocity (Gouldner, 1960), that a significant cause of an employee's helping behavior is how much organizational citizenship behavior (OCB) the employee has received from coworkers. To provide evidence of the discriminant validity of OCB received as an antecedent of helping behavior, we also assess its effects on another form of extra-role behavior, voice, as well as in-role performance. We found, in a sample of 157 employee-supervisor dyads, that OCB received was related to helping behavior after controlling for several antecedents of helping behavior identified in past research, and was less related to voice and in-role behavior, as hypothesized. Implications for theory and practice are presented.

Into the Mussa puzzle: monetary policy regimes and the real exchange rate in a small open economy

Industrial countries moving from fixed to floating exchange rate regimes experience dramatic rises in the variability of the real exchange rate. This evidence, forcefully documented by Mussa [Nominal exchange regimes and the behavior of real exchange rates: evidence and implications. Carnegie-Rochester Conference Series on Public Policy 25 (1986) 117], is a puzzle because it is hard to reconcile with the assumption of flexible prices. This paper lays out a dynamic general equilibrium model of a small open economy that combines nominal price rigidity with a systematic behavior of monetary policy able to approximate a continuum of exchange rate regimes. A version of the model with complete exchange rate pass-through is broadly consistent with Mussa’s findings. Most importantly, this holds independently of the underlying source of fluctuations in the economy, stressing the role of the nominal exchange rate regime per se in affecting the variability of the real exchange rate. However, only a model featuring incomplete exchange rate pass-through can account for a broader range of exchange rate statistics. Finally there exist ranges of values for either the degree of openness or the elasticity of substitution between domestic and foreign goods for which the baseline model is also consistent with the empirical insensitivity of output volatility to the type of exchange rate regime, as documented by Baxter and Stockman [Journal of Monetary Economics 23 (1989) 377].     

中美贸易顺差与人民币汇率关系的实证分析

针对中美贸易顺差与人民币汇率关系的问题,本文通过协整分析和Granger因果检验发现,人民币升值在短期难以对中美贸易顺差产生调节作用,从长期影响而言,人民币升值的影响作用也不大。此外,中美贸易顺差在短期还是主要取决于当前贸易收支的现实情况,而中长期则在很大程度上受到美国经济波动的影响。因此,人民币升值不会缓解美国巨大的贸易逆差,而且即使美国贸易收支出现改善也不会对美国经济发展产生显著的正面影响。     

The impact of real exchange rate shocks on manufacturing workers: An autopsy from the MORG

We study the impact of large real exchange rate shocks on workers in sectors initially more exposed to international trade using the Current Population Survey’s (CPS) Merged Outgoing Rotation Group (MORG) from 1979 to 2010 combined with new annual measures of imported inputs, a proxy for offshoring. We find that in periods when US relative prices are high, and imports surge relative to exports, workers in sectors with greater initial exposure to international trade were more likely to be unemployed or exit the labor force a year later, but did not experience significant declines in wages conditional on being employed. Contrary to the usual narrative, we find negative wage effects for higher-wage, but not lower-wage workers, particularly for those who are less-educated.     

Exploring Transition and Change in a Complex Traditional Market: The Case of the Rice Market in Bangladesh

This paper explores the unaddressed question of how the large, complex paddy‐rice market in Bangladesh is able to transform itself and evolve, in the face of changing risks and incentives, into a better‐functioning market system. It notes significant but opposing trends over two decades in different areas, particularly in terms of market structure, trade circuits and exchange relations. Evidence of a sharp decline in tied transactions points to the growing importance of impersonal exchange. The underlying causes of these changes are explored, with particular reference to microfinance, remittances, rural roads and mobile telephony.
