In this paper we provide a framework to study the aggregate dynamic behavior of an economy where individual units follow (S,s) policies. We characterize structural and stochastic heterogeneities that ensure convergence of the economy's aggregate to that of its frictionless counterpart, determine...

This paper studies the dynamic trade-off between the short-run costs and the long-run benefits of bank bailouts. In the model, banks leverage thanks to their cost advantage at monitoring firms, but hold precautionary capital buffers to avoid costly equity issuance after negative shocks. Banks'...

Driven by increased complexity of dynamical systems, the solution of system of differential equations through numerical simulation in optimization problems has become computationally expensive. This paper provides a smart data driven mechanism to construct low dimensional surrogate models. These...

Bigger governments raise the possibilities for corruption; more corruption may in turn raise the support for redistributive policies that intend to correct the inequality and injustice generated by corruption. We formalize these insights in a simple dynamic model. A positive feedback from past...

One of the most important behavioral parameters in macroeconomics is the elasticity of intertemporal substitution (EIS). Starting with the seminal work of Hall (1978), researchers haveused an Euler equation framework to estimate the EIS, relating the growth rate of consumption to the after-tax...

We develop a model where information about jobs is essentially obtained through friends and relatives, i.e. strong and weak ties. Workers commute to a business center to work and to interact with other people. We find that housing prices increase with the level of social interactions in the city...

This paper develops a tractable dynamic microeconomic model of migration decisions that is aggregated to describe the behavior of interregional migration. Our structural approach allows us to deal with dynamic self-selection problems that arise from the endogeneity of location choice and the...

In India, the first official estimate of quarterly gross domestic product (GDP) is released approximately 7-8 weeks after the end of the reference quarter. To provide an early estimate of current quarter GDP growth, we construct Coincident Economic Indicators for India (CEIIs) using a...

The result is false positive when it shows something is present when it really is not. In this paper, we develop a test for detecting false positives in dynamic economic models. We then apply this test to the New Keynesian model and the structural vector autoregression model with short-run...

We introduce a data driven and model free approach for computing conditional expectations. The new method is based on classical techniques combined with machine learning methods. In particular, we consider kernel density estimation based on simulated risk factors combined with a control variate....
