I calculate unemployment multipliers of fiscal consolidation policies in a standard, closed-economy New Keynesian framework with search and matching frictions, and, as an innovation, in the presence of sectoral heterogeneity. Family and non-family firms behave differently in the labor market and...

We present a model in which banks and other financial intermediaries face both occasionally binding borrowing constraints, and costs of equity issuance. Near the steady state, these intermediaries can raise equity finance at no cost through retained earnings. However, even moderately large...

This paper presents a non-technical overview of the recent investment literature with a special emphasis on the connection between technological progress and the investment decision. First of all, we acknowledge that some dramatic advances have been made in the 1990s in understanding and...

In this paper, we propose to explain capital accumulation in a stochastic framework by taking into account the two main motives for investment. Specifically, firms invest to expand capacity and to replace old machines. The model considers irreversible investment under uncertainty and embodied...

In this paper, we extend the usual models of irreversible investment under uncertainty by introducing the stock of public capital as an input for the private sector. Public investment takes place in a stochastic environment. Public capital then increases the productivity of private capital which...

Price setting has become more flexible following a string of large adverse shocks (Covid-19, the Ukraine War). We argue that a shift to a high-uncertainty regime incentivizes firms to invest in their ability to adjust prices. We formalize this idea in a general equilibrium model with endogenous...

In a structural dynamic model that incorporates two broad production sectors with different carbon emissions, we find that climate policy uncertainty (CPU) shocks (i) lower the market value of the highly carbon-emitting sector relative to the low carbon-emitting sector, and (ii) reduce real...

We demonstrate how the incentives of firms that partially own their suppliers or customers to foreclose rivals depend on how the partial owner can extract profits from the target. Compared to a fully vertically integrated firm, a partial owner may obtain only a share of the target's profit but...
