We introduce a notion of market times that are stochastic processes in order to represent information delay in structural credit risk models. The market times are extensions of the time change process introduced by Guo, Jarrow and Zeng in the sense that each component of the market time is not...

In this study, we investigate ordering patterns of different types of market participants in Tokyo Stock Exchange (TSE) by examining order records of the listed stocks. Firstly, we categorize the virtual servers in the trading system of TSE, each of which is linked to a single trading...

This article proposes a method to estimate relative ministerial weights in parliamentary democracies. Specifically, we present a bargaining model of government formation and estimate structural parameters of the model using data for (i) who the formateurs are, (ii) what each party's voting...

This paper empirically illustrates a new aspect of vertical integration that may hurt consumer welfare other than foreclosure and misuse of rivals' information by considering the possibility that a vertical merger turns out detrimental to the merged entity. My empirical results using data from...

This paper analyses monopolistic third-degree price discrimination in the presence of consumption externalities within two separate markets. Assuming linear inverse demands, we investigate an associated change in social welfare (the sum of the consumers' surpluses and the producer's profit) with...

This book provides an updated overview of the recent progress in the theoretical study of third-degree price discrimination. It is a marketing tactic and is said to be present if the unit price is different across different groups of buyers. Its welfare evaluation is often difficult because it...

We propose a real time benchmark for bitcoin called QRTR whose calculation is much simpler than that of BRTI. Then, we introduce two types of reference rates that are usable for daily quotes of the currency, based on QRTR. The methodologies we propose in this paper are applicable not only for...
