ENDOGENOUS FLEXIBILITY IN THE FLEXIBLE MANUFACTURING SYSTEM

We investigate the flexible manufacturing system (FMS) by using the spatial price discrimination framework of Pal. The degree of flexibility when producing variants can be increased by increasing the investment or production cost and is endogenously determined. Our result is that private incentives for increasing flexibility are excessive from a social welfare perspective.     

Alternative Approaches to Commercial Property Price Indexes for Tokyo

The paper studies the problems associated with the construction of price indexes for commercial properties that could be used in the System of National Accounts. Property price indexes are required for the stocks of commercial properties in the balance sheets and related price indexes for the land and structure components of a commercial property are required in the balance sheet accounts for the calculation of the Multifactor Productivity of the Commercial Property Industry. The paper uses a variant of the builder's model that has been used to construct Residential Property Price Indexes. Geometric depreciation rates are estimated for commercial offices in Tokyo using assessment data for REIT. The problems associated with the decomposition of property value into land and structure components are addressed. The problems associated with depreciating capital expenditures on buildings and with measuring the loss of asset value due to early retirement of the structure are also addressed.     

Bubbles,growth and imperfection of credit market in a two-country model

This study extends Hirano and Yanagawa (Rev Econ Stud 84(1):406–443, 2017) to an asymmetric two-country model and examines bubbles effects on each country’s long-run economic growth rate. This study also provides numerical examples with respect to the relationship between each country’s growth rate and their financial frictions in the balanced growth equilibria with bubbles and without bubbles. It shows that foreign bubbles have positive and negative effects on both countries’ growth rates, and which effect dominates depends on the level of financial development in both countries. In this study, the positive effect of bubbles tends to dominate when the total level of financial frictions in both countries is relatively low. When the total effect of bubbles on the growth rate is positive, the burst of foreign bubbles leads to a decrease in the growth rate in both countries. This implies that there is a positive correlation between foreign bubbles and the domestic as well as the foreign country’s growth rate.     

Separating the Age Effect from a Repeat Sales Index: Land and Structure Decomposition

Since real estate is heterogeneous and not all its quality attributes are observable, the repeat sales model pioneered by Bailey et al. (1963) has become one of the standard methods to estimate a constant-quality price index. The model, however, fails to adjust for depreciation, as age and time between sales have an exact linear relationship. This paper proposes a new method to estimate an age-adjusted repeat sales index by decomposing property value into land and structure components. As depreciation is more relevant to the structure than land, the property’s depreciation rate should depend on the relative size of land and structure. The larger the land component, the lower the depreciation rate of the property. This new method is applied to property transactions in Hong Kong and Tokyo. Hong Kong is shown to have a higher depreciation rate based on a fixed structure-to-property value ratio, while the resulting age adjustment is larger in Tokyo because its land value has shrunken over time.     

Changing employment relation systems in Japan: cases of the Mitsubishi Chemical Group and the Federation of Shinkin Banks

Over the past decade or so a number of changes have been observed in traditional Japanese employment relations (ERs) systems such as an increase in non-regular workers, a move towards performance-based systems and a continuous decline in union membership. There is a large body of Anglo-Saxon and Japanese literature providing evidence that national factors such as national institutions, national culture, and the business and economic environment have significantly influenced what were hitherto three ‘sacred’ aspects of Japanese ERs systems (ERSs). However, no research has been undertaken until now at the firm level regarding the extent to which changes in national factors influence ERSs across firms. This article develops a model to examine the impact of national factors on ER systems; and analyses the impact of national factors at the firm level ER systems. Based on information collected from two different groups of companies, namely Mitsubishi Chemical Group (MCG) and Federation of Shinkin Bank (FSB) the research finds that except for a few similarities, the impact of national factors is different on Japanese ER systems at the firm level. This indicates that the impact of national factors varies in the implementation of employment relations factors. In the case of MCG, national culture has less to do with seniority-based system. Study also reveals that the national culture factors have also less influence on an enterprise-based system in the case of FSB. This analysis is useful for domestic and international organizations as it helps to better understand the role of national factors in determining Japanese ERSs.     

COMMERCIAL PROPERTY PRICE INDEXES AND THE SYSTEM OF NATIONAL ACCOUNTS

This paper studies the problems associated with the construction of price indexes for commercial properties that could be used in the System of National Accounts (SNA). Property price indexes are required for the stocks of commercial properties in the Balance Sheets of the country. Related service price indexes for the land and structure input components of a commercial property are required in the Production Accounts of the country if the Multifactor Productivity of the Commercial Property Industry is calculated as part of the SNA. The paper reviews existing methods for constructing an overall Commercial Property Price Index (CPPI) and concludes that most methods are biased (due to their neglect of depreciation) and more importantly, not able to provide separate land and structure subindexes. A class of hedonic regression models that is not subject to these problems is discussed.     

Factors Influencing Corporate Environmental Protection Activities for Greenhouse Gas Emission Reductions: The Relationship Between Environmental and Financial Performance

This paper analyzes the relationship between a firm??s greenhouse gas (GHG) emissions and its profitability in Japanese manufacturing. Defining the difference between the marginal revenue and cost of reducing GHG emissions as the ??net benefit,?? which is endogenously characterized by various factors, we estimate a switching regression model where the sign of the net benefit determines the relationship between GHG emissions and profitability. Our empirical analysis focuses on ISO 14001 adoption, market competition, uncertainty, financial flexibility, and share ownership structure as the factors, and indicates that firms with low firm-specific uncertainty, high financial flexibility, and a high proportion of large shareholders tend to have a nonnegative net benefit, so that the positive relationship between their GHG emissions and profitability is mitigated. On the other hand, although ISO 14001 adoption is generally considered to be an indicator of a firm??s stance on environmental proactiveness, it does not provide a sufficient incentive to reduce emissions. Factors such as uncertainty, financial flexibility, and share ownership structure are more important to GHG emission reductions.     

The relationship between pollution abatement costs and environmental regulation: Evidence from the Chinese industrial sector

Since the 2000s, China has been trying to strengthen emission controls in response to increasing pollution problems. However, strict implementation of emission controls generates pollution abatement costs. Using regional data for 29 provinces in the Chinese industrial sector from 1995 to 2010, this study estimated the pollution abatement costs for each province through the measurement of environmental efficiency, by applying a directional distance function approach. Moreover, using panel data analysis, this study clarified whether there is a nonlinear relationship between pollution abatement costs and environmental regulations. The empirical results are as follows. The study confirmed that the burden of abatement costs tended not only to occur in the central and western regions but also to increase in the eastern region. Moreover, the nonlinear relationship is inverted U‐shaped; thus, pollution abatement costs increase, as a negative effect of environmental regulations, until a certain inflection point, after which they decrease.     

Collusive behavior under a leniency program

We investigate how a leniency program, which is a policy that gives reduced penalties to colluding firms that cooperate with investigations of the Antitrust Authority, affects firms’ collusive behavior. Using a model of quantity competition, we show that an amnesty to the second or later candidates of a leniency program is of no use if colluding firms can choose the most profitable collusion. Because a leniency program is a general rule that is applied to various markets in a country, our result implies that the design of a leniency program depends on which kinds of market structure are prevalent in the country.
