BIS Working Papers are written by members of the Monetary and Economic Department of the Bank for International Settlements, and from time to time by other economists, and are published by the Bank. The views expressed in them are those of their authors and not necessarily the views of the BIS. the BIS held a conference on " Understanding Low Inflation and(More)
PURPOSE We examined the change in α(1)-adrenoceptor subtype expression in the prostate due to chronic tamsulosin administration in a benign prostatic hyperplasia rat model and in patients. MATERIALS AND METHODS We measured α(1)-adrenoceptor subtype expression after tamsulosin administration in the prostate of the benign prostatic hyperplasia rat model(More)
BACKGROUND Recently, alpha(1)-adrenoceptors (alpha(1)-ARs) have been reported to play a prominent role in the growth of a variety of cells; however, little is known about prostate growth and subtype-specific effects on cell proliferation. We examined the role of alpha(1d)-AR in prostate growth and the effect of subtype-selective alpha(1)-AR antagonist,(More)
This paper examines issues surrounding monetary policy under zero interest rates based on one and a half year’s experience in Japan. After reviewing the market development in Japan, it summarizes the transmission mechanism of monetary policy under zero nominal interest rates, and considers what would be the likely policy options if a central bank were to(More)
PURPOSE Histological observations of clinical benign prostatic hyperplasia specimens show that benign prostatic hyperplasia tissue is mainly composed of stromal components, smooth muscle and fibrous tissue, so-called stromal hyperplasia. However, little is understood regarding the pathogenesis of this stromal hyperplasia due to no suitable stromal(More)
Using a model of island economy where financial markets aggregate dispersed information of the public, we analyze how two-way communication between the central bank and the public affects inflation dynamics. When inflation target is observable and credible to the public, markets provide the bank with information about the aggregate state of the economy, and(More)
Some fundamental properties of maximal open sets are obtained, such as decomposition theorem for a maximal open set. Basic properties of intersections of maximal open sets are established, such as the law of radical closure. 1. Introduction. A proper nonempty open subset U of a topological space X is said to be a maximal open set if any open set which(More)
It is known algebraically that any abelian group is a direct sum of a divisible group and a reduced group (See Theorem 21.3 of [5]). In this paper, conditions to split off rational parts in homotopy types from a given space are studied in terms of a variant of Hurewicz map, say ρ : [Sn Q ,X]→ Hn(X;Z) and generalized Gottlieb groups. This yields(More)
This paper surveys the empirical analyses that examine the effects of the Bank of Japan’s (BOJ’s) quantitative easing policy (QEP), which was implemented from March 2001 through March 2006. The survey confirms a clear effect whereby the commitment to maintain the QEP fostered the expectations that the zero interest rate would continue into the future,(More)
