We study the long-run market configurations in a quality-ladder dynamic model. Specifically, we assume that the return to investment in quality differs across the firms. That is, for a given level of investment, one firm has a higher probability to raise the quality of the good it produces. We...

The progressive wage tax is the instrument commonly used by democracies to fund public expenditures. Yet it still divides opinions about its impact on skill formation. We develop a general equilibrium model to analyze this impact, in the context of uncertain return on higher education. We show...

We study learning in perfect competition. A representative price-taking firm sells a good whose quality is unknown to some buyers. The uninformed buyers use the price to infer information about quality. Even though the firm is a price-taker, information is disseminated though the price. It is...

This paper develops a high-frequency risk measure, the Liquidity-adjusted Intraday Value at Risk (LIVaR). Our objective is to explicitly consider the endogenous liquidity dimension associated with order size. Taking liquidity into consideration when using intraday data is important because...

I hypothesize that the stock market overreacts to management earnings forecasts. I find that negative management forecast surprises lead to a -5.9% abnormal return around the forecast and a 1.9% correction in the 2-month period after earnings are announced. Positive surprises work in the...

To increase mother’s participation in the labour market and enhance child development, the Canadian province of Québec developed from 1997 a large scale low-fee childcare network. Previous studies have shown that the policy has significantly increased the labour force participation and annual...

A novel simulation-based methodology is proposed to test the validity of a set of marginal time series models, where the dependence structure between the time series is taken ‘directly’ from the observed data. The procedure is useful when one wants to summarize the test results for several...

Policy decisions affect economic outcomes, and the likelihood of observing a given state of the world. We investigate how policy choices affect learning of the true model of the economy when the policymaker’s model is mis-specified. We ask under what conditions can the central bank learn the...

We show that the composition of international trade has important implications for the optimal volatility of the exchange rate, above and beyond the size of trade flows. Using an analytically tractable small open economy model, we characterize the impact of the trade composition on the policy...

We examine how the introduction of self-control preferences influence the trade-off between two fundamental components of a public pension system: the contribution rate and its degree of redistribution. The pension regime affects individuals’ welfare by altering how yielding to temptation...
