Real Output Co‐movements in East Asia: Any Evidence for a Monetary Union?

The East Asian region has experienced astonishing economic growth and integration over the past few decades. It is generally believed that a high degree of integration in the region would greatly shape the economic structure of each individual economy and has direct implications for the effectiveness of domestic stabilisation policy and policy coordination. This paper empirically examines the feasibility of forming a monetary union in East Asia by assessing the real output co‐movements among these economies. As suggested by the optimum currency area (OCA) theory that losing monetary independence would be the major cost for adopting a common currency, it would be less costly for the economies to form a monetary union if the business cycles are synchronised across countries. The cointegration test and the Vahid and Engle (1993 ) test for common business cycles are conducted to examine their long‐run relationship and short‐run interactions in real outputs, respectively. Our study found that some pair countries in the region share both the long‐run and short‐run synchronous movements of the real outputs. In particular, the short‐run common business cycles are found in some pairs of ASEAN economies consisting of Singapore, Thailand and Indonesia, and in the Northeast Asian region consisting of Hong Kong, Korea and Mainland China, as well as between Japan and Taiwan. These findings have important implications for the economies in terms of adjustment costs when considering the adoption of a monetary union.     

Equilibrium Price Dispersion in a Matching Model with Divisible Money*

The main purpose of this article is to show that, for any given parameter value, an equilibrium with dispersed prices (two‐price equilibrium) exists in Green and Zhou's matching model with divisible money. The welfare effect of price dispersion is also analyzed.     

Linkage Formation by Small Firms: The Case of A Rural Cluster in Indonesia

This paper analyses forward linkages formed by small firms in Ceper, a rural metal-casting cluster in Central Java, and examines the effects of these linkages in promoting the firms' development. Firms in the cluster have developed subcontracting linkages with assemblers in the urban modern sector, and putting-out linkages with wholesalers located in the cities. The linkages provide benefits beyond product sales: some firms are stimulated to improve technological capabilities through subcontracting linkages with assemblers; others are supported by trade credits embedded in linkages with wholesalers. In comparing these effects with external assistance, the firms rate technological help from private institutions with a business orientation more highly than that from assemblers, and support from wholesalers more highly than any other source of financial assistance. Government assistance receives a relatively low rating. There is little evidence of effects of clustering, partly because firms consider linkages with the outer economy more strategic.     

Statistical Inference Using Stochastic Switching Models for the Discrimination of Unobserved Display Promotion from POS Data

The execution of price and/or display promotion has a significant effect on the sales of a brand sold in a supermarket. Information on price and/or sales is available from POS data. However, unless an investigator collects information on the execution of display promotions from every retail store, such information is unavailable. This paper presents a method of identifying whether display promotion has been executed without having to visit individual stores. We treat the execution/non-execution of a display promotion as a state variable. An unknown stationary probability matrix is assumed to describe the probability of a transition between states. Each state is characterized by a different stationary time series model with unknown parameters. The objective of the analysis is to identify the model and to assign a probability model for each state at each time instant. Finally, we provide a high precision estimator of a past execution/non-execution of a display promotion based on the proposed model.     

SURVEY OF RECENT DEVELOPMENTS

Managing the Indonesian economy in 2015 has proved challenging for the administration of Joko Widodo (Jokowi). In a first quarter plagued by external adversity—especially a sharp drop in exports to China—coupled with internal political paralysis and the delayed disbursement of fiscal spending, the economy recorded its lowest rate of growth since 2009. Observing relatively stable inflation, Bank Indonesia (BI), the central bank, eased its policy rate in February by 25 basis points, to 7.5%. The bank also adjusted its macroprudential measures to counter declining bank lending. On the fiscal side, the expected stimulus from fuel-subsidy reallocation and aggressive public-capital spending did not arrive. Meanwhile, tax revenue made slow progress towards its ambitious target, which it seems unlikely to attain.

Increases in supply costs made it difficult for the government to align domestic fuel prices more closely to the market. Major commodity exports fell significantly, but some manufactured exports showed hints of an upturn. The depreciation of the rupiah, the global strategies of leading investors, and the introduction of taxexemption policies that have been tested in neighbouring countries may have contributed to this trend. To further broaden the base of export diversification, the priorities should be to reduce business costs and enhance competition rather than enforce mandatory regulations. Jokowi has stressed that his focus on maritime development, part of a broader development strategy, includes reducing logistics costs.

The second quarter of 2015 saw the start of several projects in Jokowi's flagship ‘sea toll’ program to improve maritime connectivity. There is a concern, however, that the predominance of state-owned enterprises (SOEs) in strategic port operations will continue to limit competition and reduce efficiency. Jokowi's development strategy also focuses on reducing inequality. His government has implemented several distribution and redistribution policies, including the national social-security system initiated by the previous administration. The system suffered financially in its first year from low participation among those in the informal sector.     

Controls over the Development of Large Stores in Japan

This paper shows how public policy in Japan has reacted to the location and development of new large stores, and the pressures for large stores. The current policy, introduced in 1979, is attempting to limit the expansion of hypermarkets, large super-markets, discount stores, etc., and provides a mechanism and procedure for the co-ordination of future growth. The structural changes occurring in Europe are also appearing in Japan. Pre-1979 policy controls are examined, as is the 1979 legislation, together with the growth strategies of large stores in the 1980s. The paper concludes by suggesting that it will be interesting to analyse in the coming years whether Japanese policy aimed at controlling large store development is any more successful than the various, largely unsuccessful, attempts at large store control introduced by European governments.     

Growth of villages in China, 1990–2002

This paper examines the economic and noneconomic determinants of growth disparity among Chinese villages between 1990 and 2002. By estimating a growth equation, first, we confirm a significant positive effect of the initial level of human capital, as well as the initial condition of physical infrastructure. Second, social capital measured by the degree of stable social relations at the village level is also a significant growth-promoting factor. The policy implications of our findings are that public policy promoting social stability in rural areas should be strengthened, as well as increasing financial support for rural education and infrastructure construction, especially in lower income regions.     

Public pension and household saving: Evidence from urban China

We relate household savings to pension reform, to explain the high household savings rates in urban China from a new perspective. We use the exogenous – policy-induced – variation in pension wealth to estimate explicitly the impact of pension wealth on household savings, and obtain evidence of a significant offset effect of pension wealth on household savings. Although the size of the effect depends on the parameter values assumed, the finding that household savings are affected by pension reform is robust. Our estimates show that, under plausible scenarios, pension reform boosted household savings rates in 1999 by about 6–9 percentage points for cohorts aged 25–29 and by about 2–3 percentage points for cohorts aged 50–59. Our results also indicate that declining pension wealth reduces expenditure on education and health more than on other consumption items.
