We conducted business cycle accounting (BCA) using the method developed by Chari, Kehoe, and McGrattan (2002a) on data from the 1980s-1990s in Japan and from the interwar period in Japan and the United States. The contribution of this paper is twofold. First, we find that labor wedges may have been a major contributor to the decade-long recession in the(More)
The present study aimed to investigate progesterone receptor (PR) gene expression in cumulus cells and their roles during meiotic resumption of porcine oocytes. The amount of PR-A or PR-B mRNA was analyzed by RT-PCR using primer sets for the PR-B region or the PR-A/B common region. The level of PR-B mRNA in cumulus cells was up-regulated by FSH and LH(More)
The toll-like receptor (TLR) system is expressed in cumulus cells of ovulated cumulus-oocyte complexes (COCs) and is activated by bacterial lipopolysaccharides (LPS). However, the endogenous ligand(s) for the TLRs and the physiological role(s) in ovulated COCs remain to be defined. Based on reports that hyaluronan fragments can activate TLR2 and TLR4 in(More)
It has been reported that LH receptor (LHR) mRNA is not detected in cumulus cells of porcine cumulus-oocyte complexes (COCs) just after collection from small antral follicles. The present study showed that the formation of LHR in cumulus cells was up-regulated by the cultivation with 20 ng/ml FSH. When the newly synthesized receptors were stimulated by 1.0(More)
This study examines the factors that influence poor Indonesian households to invest in floating net aquaculture after being relocated due to a reservoir construction project. We take this relocation and introduction of a new technology as a natural experiment in order to identify the determinants of technology adoption. To compare three primary decision(More)

Our main data source is plant-level data collected annually by Japan's prefectural governments. The collection of these data started in 1899, and until 1911 they were brought together and published nationally in a single source, the Statistical Yearbook of the Ministry of Agriculture and Commerce (Noshokomu Tokei Nempo). Even though the national government(More)
Since its enactment in 1974 until its easing in the 1990s, the Large-Scale Retail Store Law (Daikibo Kouri Tenpo Ho) strictly regulated the entry of large-scale retailers in cities in Japan to protect local small and medium incumbent stores. This paper investigates the effect of large-scale retailers on the price level in Japan using city-level panel data(More)
