Colombia faces several challenges to secure a reliable, affordable, and climate-friendly energy supply. Persistently low reserve-to-production ratios in oil and gas, together with advancing climate change, are putting the country’s energy system at risk. Heavily relying on hydro-power, Colombia’s electricity system will become more vulnerable with extreme weather patterns such as El Niño. This paper ...
The tremendous growth of digital transactions has profoundly affected the way we interact, opening vast opportunities to improve our lives. Consumers have benefited from an unprecedented proliferation of new services and products that previously were simply too costly to be developed and marketed to customers. These digital interactions create vast amounts of data. While firms are already using...
In many dynamic decision problems, the relevant market prices and budget constraints are random variables whose realizations lie in the future. This makes optimal decision-making difficult as optimality requires an accurate quantification and interpretation of the dynamic processes operating in the market. The studies in this project model and test the agents’ expectations about relevant...
Fair Trade certification aims at transferring wealth from the consumer to the farmer; however, coffee passes through many hands before reaching final consumers. Bringing together retail, wholesale, and stock market data, this study estimates how much more consumers are paying for Fair Trade-certified coffee in US supermarkets and finds estimates around $1.50 per lb. The study then assesses how this ...
Housing prices in many countries have increased significantly over the past years, fueling a fear that speculative price bubbles will return. However, it can be difficult for policymakers to recognize when regulatory interventions in the market are necessary to counteract bubbles. This report shows how modern machine learning methods can be used to forecast speculative price bubbles at an early stage. ...
Abstract: In this paper, we analyze bidding groups that participate in procurement auctions. Our main question is to ask, whether in the absence of the joint bid, there could have been two or more independent bids and if yes, these bids yield a different final outcome. We utilize data from the Austrian construction sector and estimate models of first-price sealed-bid auctions with endogenous entry...
Joanna and Christoph will do a joint IOBB to exchange ideas on a possible project on incumbency advantage and mergers in procurement auctions. In the first part of the seminar, they will discuss possible theoreotical explanations and consequences of incumbency advantage. This will open the floor for discussion on how data from procurement auctions in the French urban transport industry can be...
The outcome of any important macroeconomic policy change is the net effect of forces operating on different parts of the economy. A central challenge facing policymakers is how to assess the relative strength of those forces. Economists have a range of tools that can be used to make such assessments. Dynamic stochastic general equilibrium (DSGE) models are the leading tool for making such assessments ...
Second generation rent control seeks to prevent negative quantity effects by exempting newly built units. The artificially lowered rent in the controlled segment makes renting attractive for households that would otherwise not have rented in the market, replacing households with higher willingness to pay for housing. These households bid up prices in the free market segment, giving rise to an opposite-sign ...
