This study is the first attempt to estimate the determinants of the operational efficiency and total factor productivity (TFP) change of major financial institutions in Cambodia during the period 2006 to 2013. The technical efficiency score and the TFP change were measured using conventional...

By using the empirical likelihood (EL), we consider the construction of pointwise confidence intervals (CIs) for nonparametric nonlinear nonstationary regression models with nonlinear nonstationary heterogeneous errors. It is well known that the EL-based CI has attractive properties such as data...

Game theory presents a useful analytical tool for addressing the problem of international cooperation and the formation of institutions. We first examine four problems that must be solved to achieve international cooperation: the common knowledge problem, agreement problem, compliance problem,...

The Japanese Consumer Price Index (CPI) is considered to be upwardly biased. This paper estimated the Engel curve based on National Survey of Family Income and Expenditure data to measure the bias. The estimated bias for the period 1989 to 2004 was 0.53 percentage points per annum. Correcting...

It has been generally assumed in the study of German urban history that the municipal electric services were brought to an end by the growth of regional power networks during the Weimar period. However, municipal electric services were not completely replaced by regional power systems. So, this...

This study proposes constructing a confidence set for the date of a one-time structural change using a point optimal test. Following Elliott and Mler (2007), we first construct a test for the break date that maximizes the weighted average of the power function. The confidence set is then...

In this paper, we analyze the formation of trusting relationships among people through communication. To foster trusting relationships, individuals must disclose private and personal information. However, disclosing such information has both costs and benefits; therefore, both parties must...

The cost of nuclear power generation critically depends on the damages caused by plant failure. We estimate the residential land damage caused by the failure of the Fukushima Daiichi nuclear power plant, as it forms a substantial part of the total damage, by observing the change in transaction...
