We consider a retailer selling new products with a returns policy. After consumers purchase products and find them undesirable, they can either return the products to the retailer or resell them individually. Both the retailer and consumers incur transaction costs in resale. Anticipating that...

Opaque selling, in which a seller offers a menu of opaque products from a collection of physical products, has been shown to be an effective strategy to segment a market and improve the seller's profit. We study opaque selling with stochastic demand and fixed initial inventory, where we consider...

Collaborative crowdsourcing communities help firms obtain ideas generated by the public sector at a lower cost compared to those generated in-house. However, the growth of these communities has led to a large influx of ideas. This has made it difficult for firm experts to identify and evaluate...

Collaborative crowdsourcing communities help firms obtain ideas generated by the public at a lower cost compared to those generated in-house. However, the growth of these communities has led to a large influx of ideas of mixed quality, which has made it difficult for firm experts to select and...

Many cities have put relentless efforts in promoting transformational changes to tackle urban challenges, accumulating considerable experiences and knowledge for other cities to learn. To reuse the successful experiences in an effective way, previous studies have developed experience mining...

We present a new volatility model, simple to implement, that combines various attractive features such as an exponential moving average of the price and a leverage effect. This model is able to capture the so-called 'panic effect', which occurs whenever systematic risk becomes the dominant...

We analyze the differential impact of the COVID-19 crisis on the Spanish labor market across population groups, as well as its implications for income inequality. The main finding is that young, less educated, and low skilled workers, as well as women are the most affected by the COVID-19 shock...

This paper estimates the effects on earnings of "gap years" between high school and university enrollment. The effect is estimated by means of standard earnings functions augmented to account for gap years and a rich set of control variables using administrative Swedish data. We find that...

We study how low interest rates in the United States affect risk taking in the market for cross-border corporate loans. Because banks tend to originate these loans with intent to sell to nonbank investors, we examine risk taking by the broad financial system. To the extent that actions of the...

We develop a theory of money and credit as competing payment instruments, then put it to work in applications. Buyers can use cash or credit, with the former (latter) subject to the inflation tax (transaction costs). Frictions that make the choice of payment method interesting also imply...
