Exchange rate volatility and Japan–U.S. commodity trade: An asymmetry analysis

Exchange rate volatility is said to affect trade flows in either direction. When increased volatility is separated from decreased volatility, asymmetric analysis reveals even more support for the fact that both increased volatility and decreased volatility affect trade flows in either direction. We add to this new literature by considering 57 industries that trade between Japan and the US. In addition to providing evidence of asymmetric response of their trade flows to a measure of exchange rate volatility, our approach identifies industries that could benefit from increased exchange rate volatility and those that could be hurt. Similarly, we identify industries that could benefit from decreased volatility and those that could be hurt. The overall conclusion is the adverse effects of dollar–yen volatility on the trade between the two countries.     

Moving Up or Falling Behind? Gender,Promotions, and Wages in Canada

We estimate that Canadian women working full time are 1.8 percentage points less likely to be promoted, receive fewer promotions, and experience 2.8 percent less wage growth following promotions than similar men. Significant “family gaps” exist among women. Women without children are less likely to have been promoted than similar men but experience similar wage growth following promotions, while women with children are as likely to have been promoted but experience less wage growth following promotions. Weekly hours and overtime hours explain significant fractions of these gender gaps. Though not precisely estimated, gender gaps in promotions also exist among part‐time workers.     

Non-linear quantile unit root test and PPP: more evidence from Africa

It is now a common practice to establish stationarity of the real exchange rate as a sign of purchasing power parity (PPP) hypothesis. In this article, we consider the real effective exchange rates of 29 African countries. When we apply conventional linear unit root tests, we find support for the PPP in eight countries. However, when we shift to the newly introduced non-linear quantile unit root test, support for the PPP increases to 15 countries.     

Children’s Food Choice: Advertised Food Type,Health Knowledge and Entertainment

The purpose of this research is to examine how the moderating effects of health knowledge (inactive vs. active) and advertising’s entertainment level (high vs. low) affect children’s response to advertising’s food content (unhealthy vs. healthy). First, a primary study using the qualitative method was conducted with the purpose of identifying healthy and unhealthy food options based on culture, eating habits, nutritional value and the access of Iranian children to each option so that they could be displayed in TV advertising, advergames and questionnaires. Then, a 2 × 2 × 2 full-factorial, randomized, mixed-effects experimental design was used to test the research framework. 330 students (aged 6–11) participated in the study. The findings revealed that children tended to choose more unhealthy foods after exposure to unhealthy food advertising. This effect was greater for a higher level of entertainment, and was successfully moderated by the activation of health knowledge. It was concluded that embedding health messages in advertising (included TV advertising and advergames) help retrieving children’s health knowledge and therefore, choosing less unhealthy food by them.     

Stability of M2 money demand function in industrial countries

In this article, we set out a model of labour productivity which distinguishes between shocks which change productivity permanently and shocks which have transient affects on productivity. We show that this model is a type of unobserved components model – a random walk with drift plus noise model. The advantage of this approach is that it provides a coherent framework to identify the deterministic trend growth component and also the productivity enhancing (or technology related) stochastic components. The model is applied to aggregate labour productivity in Australia and the time series of technology shocks extracted is used to shed some light on the contributions of policy reforms to productivity.     

The S-Curve： China versus Its Major Trading Partners

China has been accused of manipulating its currency to gain international competitiveness and enjoy a trade surplus. The S-Curve is a hypothesis that could be used to test the depreciation. It claims that while future effectiveness of currency devaluation or values of the trade balance and current exchange rate are positively correlated, the past values of the trade balance and current exchange rate are negatively correlated. While China＇s aggregate trade flows with the rest of the world conforms to the S-Curve hypothesis, disaggregating trade flows by trading partner reveals that not all partners are affected equally by devaluation. Indeed, trade with 8 out of the 24 partners does not support the S-Curve hypothesis.     

Impact of exchange rate volatility on commodity trade between US and Hong Kong

The impact of exchange rate uncertainty on trade flows is still the center of attention in international economics. A few studies that have looked at this effect in Hong Kong have used either aggregate data between Hong Kong and the rest of the world or between Hong Kong and several of her major trading partners. They have been unable to locate any significant effect. Suspecting that existing studies could suffer from aggregation bias, we concentrate on the trade between Hong Kong and the US and disaggregate their trade flows further by commodity. Out of 140 Hong Kong importing industries and 104 exporting industries considered, we find short-run effects in the majority of the industries. The short-run effects translated into the long run in 81 of Hong Kong import industries and 51 of her export industries, a finding that contradicts previous research.     

An integrated vendor–buyer model with stock-dependent demand

We develop an integrated vendor–buyer model for a two-stage supply chain. The vendor manufactures the product and delivers it in a number of equal-sized batches to the buyer. The items delivered are presented to the end customers in a display area. Demand is assumed to be positively dependent on the amount of items displayed. The objective is to maximize total supply chain profit. The numerical analysis shows that buyer–vendor coordination is more profitable in situations when demand is more stock dependent. It also shows that the effect of double marginalization provides a link between the non-coordinated and the coordinated case.     

S-curve dynamics of trade between Sweden and her trading partners

The S-curve sums up the dynamic relationship between terms of trade and trade balance. This pattern has received weak support in some developed and less developed countries when aggregate trade data are used. Empirical regularities based on aggregate trade data can be biased since aggregation can potentially suppress some of the patterns observed in trade at the bilateral level. This paper overcomes this problem by employing bilateral trade data from Sweden and finds that the S-curve is invariant to this level of disaggregation. Indeed, Sweden has a bilateral S-curve with 12 out of 17 cases examined for the 1980Q1–2005Q1 period.     

Real and Nominal Effective Exchange Rates for LDCs: 1971–2004

International Monetary Fund constructs and publishes real and nominal effective exchange rates mostly for industrial countries. Recently it has begun publishing such data for some newly industrialized developing countries as well. There remains some developing countries that still have not received any attention by the IMF. This paper bridges that gap by constructing quarterly real and nominal effective exchange rates for 11 developing countries over the 1971–2004 period. As an application we try to assess whether nominal depreciation in these countries has led to real depreciation.
