Data envelopment analysis (DEA) identifies an empirical efficient frontier of a set of peer decision making units (DMUs) with multiple inputs and outputs. The efficient frontier is characterized by the DMUs with an unity efficiency score. The performance of inefficient DMUs is characterized with...

The most prominent characteristic of the Japanese yen/U.S. dollar nominal exchange rate in the post-Plaza Accord era is near random-walk behavior sharing a common stochastic trend with the two-country monetary base differential augmented with excess reserves. In this paper, we develop a simple...

The most prominent characteristic of the Japanese yen/U.S. dollar nominal exchange rate in the post-Plaza Accord era is its near random-walk behavior sharing a common stochastic trend with the monetary base differential, which is augmented by the excess reserves, between Japan and the United...

This paper examines fiscal sustainability conditions in the Japanese economy estimating a Markov-switching vector autoregressive (VAR) model. Three fiscal sustainability conditions are identified in one VAR model: the stance of government, Domar (1944)-type GDP growth, and other factors. The...

This study empirically investigates whether macroeconomic effects of fiscal policy are affected by the existence of rule-of-thumb households in Japan. Motivated by existing theoretical formulations, we estimate a consumption function as extended to a Markov switching model and divide the sample...

For a complicated banking system with various financial attributes, there are usually different classifications of inputs and outputs from the perspectives of different stakeholders. In order to obtain the highest efficiency score, different perspectives tend to select different weight...

This study investigates the sources of Japanese business fluctuations since the 1990s, taking into account both external shocks (e.g., risk premium and foreign demand shocks) and domestic supply and demand shocks. We use the sign-restricted VAR model based on the theoretical model to identify...

The paper's main objective is to predict bank stock performance one year ahead with a composite efficiency metric from relative contextual financial analysis. We bring together financial ratios, generalized data envelopment analysis and simulated annealing to rank Japanese banks on stock...
