The (un)predictability of housing bubbles
Abstract: This paper employs econometric tests of rational bubbles, focusing on housing prices during and after the COVID-19 pandemic. I then examine monetary policy impacts on the housing bubble through a hierarchical Bayesian framework. The S&P/Case Shiller U.S. national home price adjusted by rental is considered for the empirical analysis. The findings suggest that the current housing bubble has not collapsed yet. Also, After the bubble starts, the test statistics exceed their critical values. When the bubble bursts, statistics fall below the critical values. The results also illustrate how home prices respond to the monetary policy socks.
Estimating hedonic models with endogenous marketing time using quantile regression without excluded instruments
co-authored with Jason Beck and Suyong Song.
Abstract: Hedonic modeling has been used to examine the impacts of housing characteristics on selling prices. Digressing from conventional hedonic modeling, we propose a control function approach in quantile regression models to account for heterogeneous effects of endogenous marketing time. Our approach utilizes conditional heteroscedasticity of structural errors in the triangular model as an identification strategy without excluded instruments. We document substantial heterogeneous effects of marketing time across the conditional distribution of housing prices, which show a U-shaped relationship; the marketing time impact is substantially larger for lower and higher quantiles of selling prices than for median selling price.
Does membership of the EMU matter for economic and financial outcomes?
co-authored with Kundan Kishor and Suyong Song.
Abstract: We examine treatment effects of joining the European monetary union (EMU) on macroeconomic and financial outcomes in member countries. Specifically, we apply propensity score analysis to mitigate the self-selection bias associated with the non-random nature of joining the union. The findings suggest that average treatment effect on the treated (ATT) of the EMU is associated with decline in volatility of inflation, real GDP growth and bond yields. Splitting the sample into the pre-crisis (1990-2008) and the post-crisis (2009-2019) periods and exclusion of Portugal, Ireland, Greece and Spain (PIGS) from the sample show divergent pattern of ATTs on bond yields and the debt-GDP ratio. The results suggest that the fiscal situation in the member states that excluded PIGS worsened in the pre-crisis period. We also find that PIGS benefitted from the EMU membership in terms of lower bond yields in the pre-crisis period.
Estimating loss from extreme climate events within a real options approach
co-authored with Ruth Dittrich.
Abstract: Sea level rise is a major consequences of climate change. This paper studies climate change uncertainty through an information theory framework and examines the current cost of extreme sea level rise within a real options analysis. We first propose an approach to estimate the risk-neutral density of change in global mean sea level and then use the estimated density to compute the expected overall cost from sea level rise. The proposed framework accounts for extreme sea level rise in computing the theoretical option value.
An information framework for measuring perception alignment in financial markets
co-authored with Viktoria Dalko and Hyeeun Shim.
Abstract: At the onset of the COVID-19 pandemic, the CBOE volatility index reached heights last experienced during the 2008 financial crisis. The consensus is that the World Health Organization’s announcement of the pandemic contributed to the high level of volatility. The question arises whether we have a potentially robust measure to quantify the degree that investors’ perceptions were suddenly aligned about future asset returns due to a WHO announcement. This paper provides an information framework to propose measuring the degree of perception alignment based on the perception alignment hypothesis. We provide simulation examples and illustrate empirical evidence of financial market manipulation, and estimate the loss of information due to those cases of perception alignment.
A probabilistic view to capture automation impacts
co-authored with Mariana Saenz.
Abstract: This paper examines the effects of automation on the number of transactions, sales, and cost in the foodservice industry. First, a big data tool is applied to distinguish distributions of transactions during different times of the day. Then the automation impacts on transactions are studied using a probabilistic approach in which the best fitting theoretical probability density is used in constructing simulated sampling distributions. Next, the effects of automation on sales and cost are examined through simulated forecasts and sampling distributions. The simulation studies illustrate how automation increases efficiency and improves forecasting accuracy.
