• Corruption and Renegotiation in Procurement 

  Arozamena, Leandro; Ganuza, Juan José; Weinschelbaum, Federico (RedNIE Red Nacional de Investigadores en Economía, 2024-08)

  A sponsor –e.g. a government agency– uses a procurement auction to select a supplier who will be in charge of the execution of a contract. That contract is incomplete: it may be renegotiated once the auction’s winner has ...

• On the sources of the aggregate risk premium: Risk aversion, bubbles or regime-switching? 

  Sola, Martin; Caravello, Tomás Enrique; Driffill, John; Kenc, Turalay (Journal of Economic Dynamics & Control (e-ISSN: 1879-1743), 2024-07)

  We develop and estimate a consumption-based asset pricing model that uses historical US financial data and assumes recursive utility, allowing for priced regime-switching risk and intrinsic bubbles. We also estimate ...

• Investigating symptom duration using current status data: a case study of post-acute COVID-19 syndrome 

  Rotnitzky, Andrea; Wolock, Charles J.; Jacob, Susan; Bennett, Julia C.; Elias-Warren, Anna; O’Hanlon, Jessica; Kenny, Avi; Jewell, Nicholas P.; Weil, Ana A.; Chu, Helen Y.; Carone, Marco (Arxiv, 2024-07-05)

  For infectious diseases, characterizing symptom duration is of clinical and public health importance. Symptom duration may be assessed by surveying infected individuals and querying symptom status at the time of survey ...

• On the Robustness of Mixture Models in the Presence of Hidden Markov Regimes with Covariate-Dependent Transition Probabilities 

  Sola, Martin; Pouzo, Demian; Psaradakis, Zacharias (Universidad Torcuato Di Tella, 2024-06)

  We consider general hidden Markov models that may include exogenous co- variates and whose discrete-state-space regime sequence has transition prob- abilities that are functions of observable variables. We show that the ...

• Markov-Switching Models with State-Dependent Time-Varying Transition Probabilities 

  Sola, Martin; Psaradakis, Zacharias (2017)

  This paper proposes a model which allows for discrete stochastic breaks in the timevarying transition probabilities of Markov-switching models with autoregressive dynamics. An extensive simulation study is undertaken to ...

• Inequality and technological change 

  Macera, Manuel; Tsujiyama, Hitoshi (Quantitative Economics (e-ISSN: 1759-7331), 2024)

  We study howtechnological change affects between- and within-education-group inequality in the United States. We develop a model with heterogeneous workers and firms in which the demand for skills is characterized by ...

• Prevalence of Daily Smoking and Initiation in Latin America 

  González-Rozada, Martín; Franco-Churruarin, Fiona (Health Policy Center, Institute for Health Research and Policy, University of Illinois Chicago, 2023)

  There is abundant evidence documenting the negative consequences of smoking. Over the last decades, public smoking bans, taxation, and public health tobacco control campaigns induced a decline in smoking prevalence ...
