A simple methodology is presented for modeling time variation in volatilities and other higher order moments using a recursive updating scheme similar to the familiar RiskMetrics approach. We update parameters using the score of the forecasting distribution. This allows the parameter dynamics to...

This report analyzes the start-up ecosystem in Tokyo and the greater surrounding area in Japan in the transition of the innovation model to a hybrid of traditional public sector-university-corporation research and development (R and D) combined with start-up agile innovation. It first introduces...

In this paper, we examine Chinese firms that issue both A- and B-shares in mainland China (SHSE and SZSE), which offers us a precious opportunity to study the influence of investor sentiments, holding other factors constant, on the twin stocks. We find B-share returns to commove with foreign...

We relax two common assumptions in the Hotelling model with third-degree price discrimination: inelastic demand and exogenously assumed price discrimination. Based on the constant elasticity of substitution (CES) representative consumer model, we allow firms to endogenously choose whether to...

Let $\Omega$ be one of $\X^{N 1},C[0,1],D[0,1]$: product of Polish spaces, space of continuous functions from $[0,1]$ to $\mathbb{R}^d$, and space of RCLL (right-continuous with left limits) functions from $[0,1]$ to $\mathbb{R}^d$, respectively. We first consider the existence of a probability...

Using a monthly panel dataset of individuals' debt composition including mortgage and nonmortgage consumer credit, we show that house price changes can explain a significant fraction of personal debt composition dynamics. We exploit the variation in local house price growth as shocks to...
