We solve a real business cycle model with rational inattention (an RI-RBC model). In the RI-RBC model, the growth rates of employment, investment, and output are about as persistent as in the data, with an amount of inattention consistent with survey data on expectations. Moreover, consumption,...

This paper examines the relationship between a technology shock and employment, considering price, wage rigidities, and heterogeneous agents. To explore this relationship, we utilized a Dynamic Stochastic General Equilibrium (DSGE) model, incorporating households with varying savings rates. For...

We document changes to the pattern of technology shocks and their propagation in post-war U.S. data. Using an agnostic identification procedure, we show that the dominant shock driving total factor productivity (TFP) is akin to a diffusion or news shock and that shock transmission has changed...

We implement a quantitative empirical test of the fiscal theory of the price level (FTPL) model via indirect inference, comparing it to a standard New Keynesian model. The FTPL alternative creates a serious instability problem because it triggers a 'doom loop'in which inflation pushes up...

This paper constructs speculative bubbles in a Real Business Cycle (RBC) economy. Building on Blanchard’s (Economics Letters, 1979) classic analysis of speculative bubbles in asset pricing models, the bubbles studied here result from the absence of a transversality condition for production...

We introduce a novel approach to solving dynamic programming problems, such as those in many economic models, on a quantum annealer, a specialized device that performs combinatorial optimization. Quantum annealers attempt to solve an NP-hard problem by starting in a quantum superposition of all...

We introduce a novel simulated certainty equivalent approximation (SCEQ) method for solving dynamic stochastic problems. Our examples show that SCEQ can quickly solve high-dimensional finite- or infinite-horizon, stationary or non- stationary dynamic stochastic problems with hundreds of state...

Big technological improvements in a new, secondary sector lead to a period of excitement about the future prospects of the overall economy, generating boom-bust dynamics propagating through credit markets. Increased future capital prices relax collateral constraints today, leading to a boom...

Using a unique dataset covering the universe of Portuguese firms and their credit situation we show that financially constrained firms are found across the entire firm size distribution, even in the top 1%. Incorporating a richer, empirically supported, productivity process into a standard...

This study seeks to construct a basic reinforcement learning-based AI-macroeconomic simulator. We use a deep RL (DRL) approach (DDPG) in an RBC macroeconomic model. We set up two learning scenarios, one of which is deterministic without the technological shock and the other is stochastic. The...

This paper examines the asset pricing implications of sector-specific shocks in a multi-sector economy where heterogeneous firms interact in the markets for material inputs, investment goods, and final goods. The model is solved using a third-order perturbation and is estimated by the simulated...

This paper studies the implications of procyclical capital utilization rates for inference regarding cyclical movements in labor productivity and the degree of returns to scale. We organize our investigation around five questions that we study using a measure of capital services based on...

This paper analyzes the role of variable capital utilization rates in propagating shocks over the business cycle. To this end we formulate and estimate an equilibrium business cycle model in which cyclical capital utilization rates are viewed as a form of factor hoarding. We find that variable...

Financial frictions are a central element of most of the models that the literature on emerging markets crises has proposed for explaining the Sudden Stop' phenomenon. To date, few studies have aimed to examine the quantitative implications of these models and to integrate them with an...

This paper tests the importance of technology shocks versus financial shocks for explaining, fluctuations in money. The model presented extends the theory of King and Plosser by recognizing that both money and trade credit provide transactions services. The model shows that the comovements...

When the Lucas paradigm is generalized to include real effects, the effects of real factors and monetary factors on the business cycle are always interrelated. Furthermore, in such models monetary factors can affect the long-run behavior or real output, contrary to the commonly held view that...

This paper analyzes the interaction of money and the price level with a business cycle that is fully real in origin, adopting a view which differs sharply from traditional theories that assign a significant causal influence to monetary movements. The theoretical analysis focuses on a banking...
