Re-testing Prebisch–Singer hypothesis: new evidence using Fourier quantile unit root test

The Prebisch–Singer hypothesis in economics asserts that over time the relative price of primary goods relative to manufactured goods should experience a downward trend. To test the hypothesis, we must first establish the unit root properties of the relative price term and then regress the stationary series on a trend term. We use the quantile unit root test which allows for both smooth unknown numbers and the form of breaks in the trend function through a Fourier function to show that the relative price of 23 out of 24 primary goods is stationary. However, the Prebisch–Singer hypothesis is supported only in half of the primary commodities.     

Policy Uncertainty and the Demand for Money in Korea: An Asymmetry Analysis

Previous studies included money supply volatility as well as output volatility as measures of uncertainty in estimating the demand for money. However, a more comprehensive measure of uncertainty is now constructed for many countries and is known as policy uncertainty. When we included this new measure in the formulation of the demand for money in Korea and relied upon a nonlinear specification of the money demand which allows us to assess the asymmetric effects of changes in the policy uncertainty measure, we found asymmetric long-run effects of policy uncertainty on the demand for cash in Korea. Our conjecture is that increased uncertainty induces Koreans to hold less cash in favor of safer assets and decreased uncertainty has opposite effects, though at different rate.     

Testing hysteresis effect in U.S. state unemployment: new evidence using a nonlinear quantile unit root test

We revisit hysteresis effect in the unemployment rate of each of the 52 states of the United States using nonlinear quantile unit root test over the period 1976M1–2016M7. Our results indicate that unemployment rate of the U.S. economy as a whole displays hysteresis effect over recessionary periods. Nineteen out of 52 states display hysteresis behaviour over the period 1976–2016. For the remaining 33 states, we find four types of behaviours. Some states display stationarity behaviour almost in all quantiles. Some display hysteresis over recessionary periods and in contrast some display hysteresis over expansion period.     

NONLINEAR AUTOREGRESSIVE DISTRIBUTED LAG APPROACH AND BILATERAL J‐CURVE: INDIA VERSUS HER TRADING PARTNERS

The J‐curve studies related to India have mostly either used aggregate trade flows of India with the rest of the world or between India and its trading partners. They have all assumed exchange rate changes have symmetric effects on Indian trade balance. In this article, we use partial sum concept combined with the nonlinear autoregressive distributed lag approach of Shin et al. to show that indeed in some instances, there are evidences of asymmetry effects of currency depreciation. This new nonlinear approach provides more support for the J‐curve than the previous linear approaches. (JEL F31)     

Asymmetric Effects of Exchange Rate Changes and the J‐curve: New Evidence from 61 Malaysia–Thailand Industries

Research on the impact of currency depreciation on the trade balance is now moving in a new direction by incorporating nonlinear dynamic adjustment of the exchange rate and by using a nonlinear approach to error‐correction modeling and cointegration. Using these advances, researchers find not only more evidence of the J‐curve effect, but also new evidence of asymmetric effects of exchange rate changes on the trade balance. We contribute to this line of research by using monthly trade flow data from 61 two‐digit industries that trade between Malaysia and Thailand, and show that not only does currency depreciation have favorable effects on the trade balance of more industries, but the long‐run effects are asymmetric in 26 out of 61 cases. In line with current literature, our nonlinear model performs much better than the linear model when industry level data are used.     

Creating a Space where Gender Matters: Elinor Ostrom (1933-2012) talks with Ann Mari May and Gale Summerfield

Abstract

In 2009, Elinor Ostrom received the Nobel Memorial Prize in Economic Sciences for her work, especially on governance of the commons. Trained as a political scientist, Ostrom embraced interdisciplinary research and transdisciplinary collaboration. Ann Mari May and Gale Summerfield's interview with Ostrom, conducted in fall 2011, illustrates the relevance of her work to feminist economics as well as her impressive accomplishments as the first woman recipient of the Nobel prize in economics and as a pioneering woman in academia. Ostrom died on June 12, 2012.     

Women’s snowboarding – some experiences and perceptions of competition

This article focuses on female snowboarders’ experiences with, and perceptions of, snowboard competitions. The article is based on a study conducted at an international women’s snowboard camp. The purpose of the camp was to discuss strategies for promoting females’ participation in the snowboard organisations and in snowboard competition. Interviews were held with eight participants aged 18–31?years. Most of the participants had been previously involved in competition. Their experience had been both negative and positive. Most of the participants perceived snowboard facilities (Big air and Half-pipe) as being too large for females and a possible constraint on participation. Moreover, the study’s findings reveal ideas concerning alternative competition formats as well as arguments for ‘women-only’ sessions as a feasible way to reach more female snowboarders, to provide skill enhancement, and to increase participation in the competitions. The findings are discussed in light of the development of snowboarding and Bourdieu’s theoretical framework.     

The J-curve: evidence from commodity trade between US and China

In testing the short-run (J-curve effect) and the long-run effects of currency depreciation on the trade balance many researchers have used either trade data between one country and the rest of the world or between one country and another trading partner. Both groups are said to suffer from aggregation bias. To reduce the bias, in this article we consider trade data between one country (the US) and her trading partner (China) disaggregated by commodity. We use imports and exports of 88 industries (2-digit and 3-digit classifications) and cointegration analysis to show that the trade balance of at least 34 of the industries react favourably to real depreciation of the dollar. The J-curve effect is detected in 22 industries. Furthermore, most of these industries that are sensitive to currency depreciation are durable commodity groupings.     

Exchange‐rate volatility and US–Hong Kong industry trade: is there evidence of a ‘third country’ effect?

In an effort to better understand the determinants of trade flows worldwide, researchers have recently incorporated external volatility (in addition to that of the partners’ bilateral exchange rate) into their models. The so‐called ‘third country’ effect is present if adding this term changes the bilateral volatility estimates that are found when external volatility is omitted. This study examines US exports to Hong Kong for 143 industries, and imports from Hong Kong for 110 industries, and finds two key results. First, expected inflation due to Hong Kong's dollar peg leads to increased US exports in a large number of industries. Second, comparing our results with those of a previous study shows strong evidence of a ‘third country’ effect, especially for US imports. Nonparametric tests suggest that these effects differ by sector: for both exports and imports. Manufacturing industries that enjoy a large trade share are less likely to experience this effect once external volatility is incorporated into the analysis.     

Performance-related pay and gender wage differences

We study the impact of performance-related pay (PRP) on gender wage differences using Finnish-linked employer–employee panel data. Controlling for unobserved person and firm effects, we find that bonuses increase women’s earnings slightly less than men’s, but the economic significance of the difference is negligible. Piece rates and reward rates, however, tend to increase gender wage differentials. Thus, the nature of a PRP plan is important for gauging the impact of PRP on gender wage differentials. A comparison with OLS results shows the importance of controlling for an unobserved person and firm effects.
