Is devaluation expansionary or contractionary? Empirical evidence from Fiji

Devaluation has been traditionally promoted as an effective tool for increasing exports and improving the external position of the devaluing country if a nominal devaluation results in expenditure switching. In this article, our aim is to model the relationship between currency devaluations and output for Fiji. Following the approach in Bahmani et al. (2002 Bahmani-Oskooee, M, Chomsisengphet, S and Kandil, M. 2002. Are devaluations contractionary in Asia?. Journal of Post Keynesian Economics, 25: 69–81. [Taylor &; Francis Online] , [Google Scholar]), we extend the traditional model by incorporating other monetary and fiscal policy variables. We achieve our goal by using the recently developed bounds testing approach to cointegration and the autoregressive distributed lag model and find that devaluation is expansionary in the case of Fiji.     

Are financial returns really predictable out-of-sample?: Evidence from a new bootstrap test

Testing the out-of-sample return predictability is of great interest among academics. A wide range of studies have shown the predictability of stock returns, but fail to test the statistical significance of economic gains from the predictability. In this paper, we develop a new statistical test for the directional accuracy of stock returns. Monte Carlo experiments reveal that our bootstrap-based tests have more correct size and better power than the existing tests. We use the forecast combinations and find that the stock return predictability is statistically significant in terms of reduction of mean squared predictive error relative to the benchmark of historical average forecasts. However, the results from our tests show that the predictability is not economically significant. We conclude that there will be still a long way to go for forecasting stock returns for market participants.     

Revisiting the sectoral Linder hypothesis: Aggregation bias or fixed costs?

This paper reassesses and revisits the Sectoral Linder Hypothesis due to Hallak, which posits that similar tastes for quality lead to more intensive trade between similar countries at the sectoral level. First, the measure of demand similarity used in this paper is based on the distribution of income estimated from household surveys. The paper finds that a similarity measure based on the income distribution produces stronger results than the traditionally used measure based on GDP per capita. Moreover, the country/product level extensive margin is taken into account. This is important because similarity is likely to affect the fixed costs of trade and the fixed costs of alternative means of servicing a market (i.e., licensing and FDI). Fixed costs, in turn, affect the number and average productivity of firms that engage in bilateral trade and hence the overall volume of trade. This paper employs the method by Helpman et al. to control for the extensive margin. Heteroskedasticity is addressed using a feasible generalized least squares (FGLS) approach. The findings show that once controlling for the effect of similarity on the extensive margin, the Linder hypothesis holds at more aggregate levels. Other robustness checks suggest that results are not confined to products that are vertically differentiated.     

Sticky prices or rational inattention – What can we learn from sectoral price data?

This paper derives stylised facts on sectoral inflation dynamics and confronts these facts with two popular theoretical models of price setting. Based on sectoral price responses to macroeconomic shocks estimated from an approximate factor model, we find that the frequency of price changes explains a relevant share of the cross-sectional variation of the speed and size of responses. Moreover, there is little evidence that the volatility of sectoral inflation due to idiosyncratic shocks dampens the size and speed of the responses to macroeconomic shocks. These findings support a multi-sector model with sticky prices rather than a rational-inattention model. We derive the results from different modelling and sampling decisions proposed in the literature, and we find that the explanatory power of the frequency of price changes for the speed of response to a macroeconomic shock proves robust in the face of these decisions. Other results are sensitive with respect to the choice of the factor model and the treatment of outliers.     

Are natural gas spot and futures prices predictable?

We answer two questions concerning natural gas spot and futures prices. The first is: Can natural gas futures prices predict natural gas spot prices? The second is: Are natural gas spot and futures prices weak form efficient or can they be predicted based on examination of historical data? To answer these questions, we use daily data for Henry Hub natural gas spot and futures prices. Our answer to the first question is that natural gas futures prices do not predict the magnitude of future natural gas spot prices any better than what would be predicted by a random walk model. This result has important implications for many financial analysts and policy institutions that have used commodity futures prices to predict movements in spot prices. The answer to the second question is that when we apply a unit root test that allows for heteroskedasticity and two structural breaks, natural gas spot and futures prices are predictable. We then simulate a contrarian trading strategy for spot and futures prices to show under what circumstances trading in spot and futures prices are also profitable. The results point to the need to accommodate heteroskedasticity when applying unit root tests to model energy spot and futures prices with high-frequency data, such as daily data.     

Disparities in Australian Regional Incomes: Are They Widening or Narrowing?

In this study we examine Australian census data on regional incomes for the period 1976–91. Following a discussion of theories and empirical evidence regarding regional income adjustment, the regional dispersion of per capita income is analysed for the six Australian states and at the sub-state level (statistical divisions, SDs). The coefficient of variation is used as the measure of dispersion, and Gini coefficients are also calculated to analyse income equality within regions. For Australia, the cross-state dispersion of per capita incomes increased over the period, whereas there was neither convergence nor divergence of incomes among Australia's 57 SDs. In addition, the intrastate dispersion of per capita incomes across SDs remained largely unaltered over the period. Gini coefficients indicated that across income strata, the distribution of incomes both within states and within SDs has become more equal.     

Are shocks to foreign investment in developing countries permanent or temporary? : Evidence from panel unit root tests

We examine the time path of foreign direct and portfolio investment in developing countries to test if shocks have permanent or temporary effects. Our findings indicate that shock effects are temporary. The results are robust to the strictness of balance of payment controls.     

Are children an incentive or a disincentive for migration? Evidence from Vietnam

This study analyzes the influence of children on household migration decisions using data on current internal movement in Vietnam a country that has experienced significant rural–urban migration in the recent years. Families with children usually have three migration choices: move together, stay together or send only one parent to work afar. Using an instrumental variable approach, we show that having an additional child reduces the probability of household migration by 0.0115, while it increases the likelihood of fathers’ migration by 0.0121. These effects suggest that households with more children may be less mobile but may have a greater economic need for migration.     

Relative Income Position and Happiness: Are Cabinet Supporters Different from Others in Japan?

During the period of 2001–2006, the Liberal Democratic Party (LDP) adopted a market‐oriented policy under the Koizumi cabinet. Using data covering the Koizumi and first Abe cabinets, the present paper attempts to examine whether the effects of relative income differ between supporters and non‐supporters of the Koizumi cabinet. Key findings are as follows: within the Koizumi cabinet period, a relatively low‐income position is negatively related to happiness for non‐LDP supporters but not for LDP supporters. However, under the period of the first Abe cabinet, the difference in the effect of relative income for LDP supporters and others disappears. These results imply that an expectation of market outcomes leads to a difference in the effect of relative income position on happiness levels.     

Are momentum traders different? Implications for the momentum puzzle

This article examines the puzzlingly high unexploited momentum returns from a new perspective. We analyse characteristics of momentum traders in a sample of 692 fund managers. We find that momentum traders are ‘defined’ by their short-term horizon, by a behavioural view on the market and by a somewhat lower degree of risk aversion, whereas they are like other fund managers with respect to sophistication. This is consistent with the interpretation that momentum returns may compensate for the risk of momentum trading on short-term horizons and that the short-term oriented momentum traders are not in a position to perform long-term arbitrage.     

Hysteresis in unemployment: Fact or fiction?

A stylized fact of European unemployment dynamics is one of extreme persistence and possible unit root behavior. This has led to a major reconsideration of the natural rate paradigm. We apply the Kalman filter to estimate the natural rate of unemployment for Germany and France. When the moving natural rate model is tested against the alternative of a unit root process, the unit root hypothesis is resoundingly rejected.     

Was the recent downturn in US real GDP predictable?

This article uses a small set of variables – real GDP, the inflation rate and the short-term interest rate – and a rich set of models – atheoretical (time series) and theoretical (structural), linear and nonlinear, as well as classical and Bayesian models – to consider whether we could have predicted the recent downturn of the US real GDP. Comparing the performance of the models to the benchmark random-walk model by root mean-square errors, the two structural (theoretical) models, especially the nonlinear model, perform well on average across all forecast horizons in our ex post, out-of-sample forecasts, although at specific forecast horizons certain nonlinear atheoretical models perform the best. The nonlinear theoretical model also dominates in our ex ante, out-of-sample forecast of the Great Recession, suggesting that developing forward-looking, microfounded, nonlinear, dynamic stochastic general equilibrium models of the economy may prove crucial in forecasting turning points.     

Do asset sales lead to improvements in operating performance?

The changes in operating performance associated with asset sales are investigated for a sample of UK firms. Asset sales are followed by an improvement of 11% per annum in the level of operating performance relative to the pre-sale performance level. Further, improved abnormal operating performance is found, which is measured after controlling for the performance of the industry, the pre-sale performance of the firm and the level of competition in the market for asset sales. The abnormal operating performance of the remaining assets improve by 2.4% per annum, on average, for three years after the asset sales. This study also finds that the market for asset sales is imperfectly competitive.     

Monetary policy under flexible exchange rates: When is expansion contractionary?

This paper studies whether the observed instability in the effects of monetary policy could be due to the way in which the behavior functions have been specified in an open economy context. Accordingly, special emphasis is on the specification of the behavior functions to correspond to their foundations in closedeconomy macrotheory. The demand for real money balances, in terms of the expenditure basket of goods, is specified as a function of income in terms of the same basket. Imports are specified as a function of expenditures, being functionally part of expenditures. The supply of labor is specified as a function of the expenditure price.It is shown that the exchange rate overshoots but output declines, to eventually rise above its original level in response to monetary expansion in the real wage model. In the money wage model, output and the exchange rate overshoot their steady-state levels if the expansion eventually leads to an increase in nominal wealth. If it leads to a decrease, both variables undershoot. However, if interest payments on foreign securities are not small relative to the trade balance, many of the effects are reversed. Thus the overshooting result is far from robust even in a standard model with an exogenous money supply.     

Are Women Less Capable in Managing Crops? Insights from Cotton Production in Northern China

Women’s performance in agriculture matters, as women are becoming increasingly involved in agricultural production worldwide. Many studies have demonstrated that women-led farms perform less well as a result of less access to production factors, but no studies focus on how women perform without this constraint. This study fills that gap by analyzing the case of cotton cropping, which is known for its high labor requirements, high production inputs, and need for technical knowledge. Using primary data collected in northern China over the 2006–9 period, it uses the concept of “Daily Crop Management” (DCM) and identifies DCM farms managed by women whose husbands were engaged in off-farm activities on a long-term basis. The study finds that one-third of all farms were female-DCM farms, that these were smaller than those of their male counterparts but had equal access to production factors and achieved equal if not better technical and economic performances.
