Some international evidence on the stability of aggregate import demand function

This paper empirically analyses the stability of the aggregate import demand function for G7 countries. The standard cointegration test and a test developed by Gregory and Hansen are performed. The results of standard cointegration tests suggest that there is no stable cointegrating relation between real import, real GDP and relative import price for all G7 countries. The cointegrating relation is empirically supported for France and Germany if structural change for cointegrating vector is explicitly taken into consideration. The cointegrating relation is empirically rejected for Canada, Italy, Japan, the UK and the USA. Thus, the stimulation of domestic business conditions will not necessarily link the quantity of imports for these five countries.     

Sequential product positioning in the presence of an asymmetric network externality intensity

In this study, we analyze the sequential decisions on product positioning of two firms in the presence of network externalities. One commonly accepted phenomena in a market where a network externality arises is the first‐mover advantage, in which the first entrant into a market can earn a higher profit than later entrants. However, in some recent online services markets, we see that the second mover earns a higher profit than the first mover. This occurs because the second mover strengthens its variety of available functions and services markedly, thereby facilitating consumers' work and communication with its main product, which we call network externality intensity. Based on this observation, we analyze sequential positioning in Hotelling's framework by incorporating an asymmetric network externality intensity between firms. We show that unlike the results of previous related studies, both first‐ and second‐mover advantages can appear in the equilibrium depending on the relationship of the network externality intensity between firms; further, they do not change monotonically with the level of network externality intensity.     

Political Accountability,Electoral Control and Media Bias

Are anti‐establishment mass media really useful in preventing politicians from behaving dishonestly? This paper models the direction of media bias, and shows that the probability of a dishonest action by an incumbent is higher (than that in the case of no media bias) if and only if the mass media have some degree of “anti‐incumbent” bias (i.e. information favourable to the incumbent is converted into unfavourable news about the incumbent with a positive probability), provided that the incumbent is less likely to be opportunistic than a challenger in the upcoming election. This result holds irrespective of the degree of “pro‐incumbent” bias.     

Dynamic effects of government expenditure in a finance constrained economy

This paper introduces constant government expenditure in Woodford's finance constrained model (J. Econ. Theory, 1986) with capital-labor substitution as presented in Grandmont, Pintus and de Vilder (J. Econ. Theory, 1998) and investigates how government expenditure influences local dynamics near multiple steady states, depending upon the elasticity of substitution between capital and labor in production.     

Structural and cyclical movements of the current account in Japan: An alternative measure

The purpose of this study is to analyze fluctuations in the current account in Japan by deconstructing structural and non-structural components with a new method. The study shows that at the beginning of the 1980's, most components of the current account in Japan were structural. After the Plaza agreement in 1985, however, Japan's structural current account sharply decreased. Since the end of 1990s, the structural components increased again and reached nearly 2% of GDP and these movements are generally associated with the structural components of equipment investment. Business fluctuations in Japan and world, especially in the U.S. play an important role in the non-structural current account. Cyclical movements of the current account are remarkable because they include periods of recession, and this tendency was notable in the 1990s.     

Directional analysis of consumers’ forecasts of inflation in a small open economy: evidence from South Korea

We evaluate the directional accuracy of consumers’ forecasts of inflation in predicting the movement of the actual CPI in a small open economy. In order to do so, we use a method developed by Pesaran and Timmermann (2009), based on South Korean data. By illustrating an application of the new market-timing test, we show that consumers’ expectations of inflation are not a useful predictor of the CPI in South Korea. Our findings suggest that the directional accuracy of consumers’ 1-year-ahead forecasts of inflation is not affected by the inflation targeting of the Bank of Korea. Our findings also suggest that consumers’ 1-year-ahead forecasts of inflation are scattered away from the Bank of Korea’s inflation target.     

Chronic Deflation in Japan

Japan has suffered from a long‐lasting but mild deflation since the latter half of the 1990s. Estimates of a standard Phillips curve indicate that a decline in inflation expectations, the negative output gap, and other factors such as a decline in import prices and a higher exchange rate all account for some of this development. These factors, in turn, reflect various underlying structural features of the Japanese economy. This paper examines a long list of these structural features that may explain Japan's chronic deflation, including the zero lower bound on the nominal interest rate, public attitudes toward the price level, central bank communication, weaker growth expectations coupled with declining potential growth or the lower natural rate of interest, risk‐averse banking behavior, deregulation, and the rise of emerging economies.
