This dissertation deals with two important research problems in computer networks: resource allocation and caching. It consists of three essays in the broad research areas mentioned above. Essay 1 presents a pricing and allocation mechanism for peer-to-peer (P2P) networks. A P2P system can be...

A key question for Internet commerce is the strategic implications of technological advancements that distinguish the Internet channel from the traditional channels. One important distinction is that website technologies lead to a lower search cost on the Internet. Consequently, Internet...

This paper explores the impact of exchange rate fluctuations on exported product quality. Existing studies of quality upgrading stress the link between home country depreciation and increased access to export markets. Our focus in this study is on the complimentary effect of an import currency...

This paper investigates the heterogeneous and time-varying effects of financial credits on firm-level export performance. Using a data set covering comprehensive Chinese manufacturing firms and employing a difference-in-differences approach, we find that financial credits improve firm-level...

This paper investigates how Technical Barriers to Trade (TBT) affect firm export performance. The implementation of the “Children-Resistance” act (CR act) in the EU offers an ideal quasi-natural experiment to identify the causal effect of TBTs on firm performance. Using data on Chinese firms...

This paper quantifies the separate contribution of idiosyncratic productivity and demand growth on aggregate Chinese exports. We develop firm, product, market and year specific measures of productivity and demand. We use these measures to document a number of novel findings that distinguish the...

This paper extends the model of Antras et al.(2014) to disentangle the link between demand shocks and firm-level offshoring decisions. The model predicts that a positive demand shock increases the firm-level purchases of imported intermediates in both the extensive and intensive margins. Using a...
