Distributions for returns are used to compute the capital charge for portfolios in investment banks. The mainstream definition of returns is based on closing prices and neglects the important effects of intraday trading activity on the losses . In this paper we introduce ''minimal returns'', a...

This paper addresses the striking ability of transaction flows to explain exchange rate movements. Specifically, we examine whether this arises because transaction flows convey incremental information about fundamentals. If so, then these flows should affect price upon their realization and...

This paper provides an overview of the recent literature on Foreign Exchange Market Microstructure. Its aim is not to survey the literature, but rather to provide an introductory tour to the main theoretical ideas and empirical results. The central theoretical idea is that trading is an integral...

This paper compares the true, ex-ante forecasting performance of a micro-based model against both a standard macro model and a random walk. In contrast to existing literature, which is focused on longer horizon forecasting, we examine forecasting over horizons from one day to one month (the...

We consider an economy with incomplete markets and a single ¯rm and assume that utility can be freely transferred in the form of the ini- tially available good 0 (quasilinearity). In this particularly simple and transparent framework, the objective of a firm can be defined as the max- imization...

We consider economies with incomplete markets, production, and a given distribution of initial endowments. The main purpose of the paper to present a robust example of an econmy with only one firm and one good per state in which no production dicision entails a constrained efficient outcome. In...

Estimation of the parameters of Garch models for financial data is typically based on daily close-to-close returns. This paper shows that the efficiency of the parameter estimators may be greatly improved by using volatility proxies based on intraday data. The paper develops a Garch quasi...

We propose a general class of non-constant volatility models with dependence on the past. The framework includes path-dependent volatility models such as that by Hobson&Rogers and also path dependent contracts such as options of Asian style. A key feature of the model is that market completeness...

Our paper examines the volatility spillover between the stock market and the foreign exchange market in Pakistan. For the longrun relationship we use the Engle Granger two-step procedure and the volatility spillover is modelled through the bivariate EGARCH method. The estimated results from...
