In this paper, we systematically analyze the empirical importance of standard conditions for the validity and generalizability of field experiments: the internal and external overlap and unconfoundedness conditions. We experimentally varied the degree of overlap in disjoint sub-samples from a...

To help households and firms with exploding energy costs in the aftermath of the Ukraine war, a new policy called the "energy price brake" was implemented. A unique feature of this relief measure is that it provides a transfer that increases in the consumer's contractual per-unit price of...

We study the timing of new technology adoption in markets with input outsourcing, and thus with vertical relations. We find that technology adoption can take place earlier when firms engage in input outsourcing than when they produce the input in-house. Hence, the presence of vertical relations...

In a two-tier oligopoly, where the downstream firms are locked in pair-wise exclusive relationships with their upstream input suppliers, the equilibrium mode of competition in the downstream market is endogenously determined as a renegotiation-proof contract signed between each downstream firm...

This paper examines how delivery tariffs and private quality standards are determined in vertical relations that are subject to asymmetric information. We consider an infinitely repeated game where an upstream firm sells a product to a downstream firm. In each period, the firms negotiate a...

This paper investigates the effects of changes in retail market concentration when input prices are negotiated. Results are derived from a model of bilateral Nash-bargaining between upstream and downstream firms which allows for general forms of demand and retail competition. Whether...

This paper demonstrates that the standard conclusions regarding the comparison of Cournot and Bertrand competition are reversed in a vertically related market with upstream monopoly and trading via two-part tariffs. In such a market, downstream Cournot competition yields higher output, lower...

We explore the strategic role of private quality standards in food supply chains. Considering two symmetric retailers that are exclusively supplied by a finite number of producers and endogenizing the suppliers' delivery choice, we show that there exist two asymmetric equilibria in the...

This paper studies unshrouding decisions in a framework similar to Gabaix and Laibson (2006), but considers an alternative unshrouding mechanism where the impact of advertising add-on information depends on the number of unshrouding firms. We show that shrouding becomes less prevalent as the...

We analyze the best price clauses (BPCs) of online travel agents (OTAs) using meta-search price data of nearly 30,000 hotels in different countries. We find that BPCs influence the pricing and availability of hotel rooms across online sales channels. In particular, hotels publish their offers...
