Land and labor reallocation in pre-modern Japan : a case of a northeastern village in 1720-1870

In agricultural societies, adjusting land and labor according to changes of labor endowment that result from family life cycle events is premised on making full use of resources for each farming household and for the economy as a whole. This paper examines how and how well households in pre-modern Japan reallocated land and labor, using a population register covering 150 years from 1720–1870 for a village in the Tohoku region. We find that households reacted to equalize their production factors; land-scarce households tended to acquire or rent-in land and out-migrate their kin members, while land-abundant households tended to release or rent-out land, in-migrate kin members, or employ non-kin members. Estimates suggest that more than 80% of the surplus or deficit area of land was resolved if the household rented or "sold" land. We discuss a potential underlying mechanism; namely, that the village's collective responsibility for tax payment (murauke) motivated both individual households and the village as a whole to reallocate land and labor for the efficient use of resources.

Should energy efficiency be traded off for other product attributes? : an analysis of air-conditioner regulation in Japan

This paper examines the functioning of energy efficiency standards and labeling policies for air conditioners in Japan. The results of our empirical analysis suggest that consumers respond more to label information, which benchmarks the energy efficiency performance of each product to a pre-specified target, than to direct performance measures. This finding provides justification for the setting, and regular updating, of target standards as well as their use in calculating relative performance measures. We also find, through graphical analysis, that air conditioner manufacturers face a tradeoff between energy efficiency and product compactness when they develop their products. This tradeoff, combined with the semi-regular upward revision of minimum energy efficiency standards, has led to the growth in indoor unit size of air conditioners in recent years. In the face of this phenomenon, regulatory rules were revised so that manufacturers could adhere to less stringent standards if the indoor unit size of their product remains below a certain size. Our demand estimates provide no evidence that larger indoor unit size causes disutility to consumers. It is therefore possible that the regulatory change was not warranted from a consumer welfare point of view.

Dynamics of investment negotiations between China and Japan : the China-Japan-Korea trilateral investment treaty and beyond

The investment agreement relationship between China and Japan is complex. The many intersecting and overlapping agreements can rightly be described as a "noodle bowl of agreements." The 1989 bilateral investment treaty (BIT) between China and Japan still stands. Japan can also free-ride on the negotiation outcome of China's BITs and free trade agreements (FTAs) with other countries by using the most-favored-nation (MFN) provision in the 1989 China-Japan BIT, which does not contain regional economic integration organization (REIO) exception rules. However, because the China-Japan BIT does not have investor-state dispute settlement (ISDS), it may face implementation problems. The China-Japan-Korea trilateral investment treaty (CJK TIT), in force since 2014, made improvements upon the 1989 BIT, but Japan is not entirely satisfied with the outcome. For Japan, pre-establishment national treatment (NT) and prohibition of various types of performance requirements are the most important negotiation items, but the CJK TIT insufficiently addressed those problems. Moreover, because the CJK TIT has MFN provisions with an REIO exception rule, better access to investment markets brought about by future FTAs such as the China-Korea FTA and the EU-China FTA cannot be imported into CJK TIT. Hence, in the long run, Japan needs to pursue an FTA investment chapter with China that covers both MFN and ISDS.
