The use of static-demand systems in empirical analysis assumes that consumers adjust immediately to a new long-run equilibrium path when a shock is encountered. However, adjustment is not always instantaneous. This paper utilizes an Error-Corrected Linear Approximate Almost Ideal Demand System...

In this paper, we introduce a new approach to estimating differentiated product demand systems that allows for products with zero sales in the data. Zeroes in demand are a common problem in differentiated product markets, but fall outside the scope of existing demand estimation techniques. We...

Nutritional transition - the changes in food consumption patterns from a healthy diet to an unhealthy diet, is identified as one of the leading causes of rising Non-Communicable Diseases (NCDs) in Law and Middle-Income Countries (LMICs). Using food demand elasticities, estimated through the...

Financial contagion has been widely recognized as a fundamental risk to the financial system. Particularly potent is price-mediated contagion, wherein forced liquidations by firms depress asset prices and propagate financial stress, enabling crises to proliferate across a broad spectrum of...

The increasing availability of retail scanner data makes it possible to study consumer demand at more disaggregated levels than ever before. This paper derives the asymptotic properties for a tractable iterated three stage least squares (I3SLS) estimator and applies it to estimate a quadratic...
