Nirei and Scheinkman (2021) proposed an equilibrium model of price adjustments with menu-costs with a finite number of firms and derived a "reproduction number" for repricing and a limit functional form for the distribution of the number of simultaneously price-adjusting firms. We show that the...

Nirei and Scheinkman (2021) proposed an equilibrium model of price adjustments with menu-costs with a finite number of firms and derived a "reproduction number" for repricing and a limit functional form for the distribution of the number of simultaneously price-adjusting firms. We show that the...

The first half of the paper is devoted to description and implementation of statistical tests arguing for the presence of a Brownian component in the inventories and wealth processes of individual traders. We use intra-day data from the Toronto Stock Exchange to provide empirical evidence of...

We propose a decomposition of algorithm's a priori performance, from which we sep- arate contributions came from different factors. We show that, in combining estimations on volume and price and always taking into account the price-impact effect, one is able to optimize the execution in a...

The tick value is a crucial component of market design and is often considered the most suitable tool to mitigate the effects of high frequency trading. The goal of this paper is to demonstrate that the approach introduced in Dayri and Rosenbaum (2015) allows for an ex ante assessment of the...

In this paper, we use a database of around 400,000 metaorders issued by investors and electronically traded on European markets in 2010 in order to study market impact at different scales.At the intraday scale we confirm a square root temporary impact in the daily participation, and we shed...

We consider a stochastic game between three types of players: an inside trader, noise traders and a market maker. In a similar fashion to Kyle's model, we assume that the insider first chooses the size of her market-order and then the market maker determines the price by observing the total...

In this paper we propose a method to breakdown any price change at any scale time into a book-driven component and a deal driven component.Following recent empirical researches on orderbook dynamics, we build an estimate of the most probable next traded price (i.e. "expected price''...

We study the simplest discrete-time finite-maturity model in which default arises when the firm is not able to pay its debt obligation using the current cash-flow plus the corporate liquidity. An important distinction is made between liquidity and solvency of the firm. The corporate financial...
