House Price Booms and the Current Account

A simple open economy asset pricing model can account for the house price and current account dynamics in the G7 over the years 2001-2008. The model features rational households, but assumes that households entertain subjective beliefs about price behavior and update these using Bayes' rule. The resulting beliefs dynamics considerably propagate economic shocks and crucially contribute to replicating the empirical evidence. Belief dynamics can temporarily delink house prices from fundamentals, so that low interest rates can fuel a house price boom. House price booms, however, are not necessarily synchronized across countries and the model correctly predicts the heterogeneous response of house prices across the G7, following the fall in real interest rates at the beginning of the millennium. The response to interest rates depends sensitively on agents' beliefs at the time of the interest rate reduction, which are a function of the prior history of disturbances hitting the economy. According to the model, the US house price boom could have been largely avoided, if real interest rates had decreased by less after the year 2000.interest rates, house prices, short-term capital movements

Long-Run Growth Uncertainty

Observed macroeconomic forecasts display gradual recognition of the long-run growth of endogenous variables (e.g. output, output per hour) and a positive correlation between long-run growth expectations and cyclical activities. Existing business cycle models appear inconsistent with the evidence. This paper presents a model of business cycle in which households have imperfect knowledge of the long-run growth of endogenous variables and continually learn about this growth. The model features comovement and mutual influence of households' growth expectations and market outcomes, which can replicate the evidence, and suggests a critical role for shifting long-run growth expectations in business cycle fluctuations.

A Model of housing and credit cycles with imperfect market knowledge

The paper presents a model of housing and credit cycles featuring distorted beliefs and comovement and mutual reinforcement between house price expectations and price developments via credit expansion/contraction. Positive (negative) development in house prices fuels optimism (pessimism) and credit expansion (contraction), which in turn boost (dampen) housing demand and house prices and reinforce agents' optimism (pessimism). Bayesian learning about house prices can endogenously generate self-reinforcing booms and busts in house prices and significantly strengthen the role of collateral constraints in aggregate fluctuations. The model can quantitatively account for the 2001-2008 U.S. boom-bust cycle in house prices and associated household debt and consumption dynamics. It also demonstrates that allowing for imperfect knowledge of agents, a higher leveraged economy is more prone to self-reinforcing fluctuations

A Note on learning in a credit economy

This paper studies the interaction of agents' collateral price beliefs, credit constraint and aggregate economic activity over the business cycle. Learning strengthens the role of collateral constraints in aggregate fluctuations. Under heterogeneous learning rules, numerical simulations illustrate that bankruptcy on the part of borrowers arises sooner as they track the economy faster

Great or grim? Disagreement about Brexit, economic expectations and household spending

Does political polarization influence economic expectations and behaviour? Utilizing British household surveys and administrative data, we find a strong polarization of economic expectations and behaviour between pro- and anti-Brexit supporters after the once-in-alifetime EU Referendum. We show that the Brexit vote led to a large and long-lasting divergence between Leavers and Remainers in their assessment of the general economic situation, personal circumstances, and spending intentions. Furthermore, on average, a 10% difference in the share of leave voters across local authorities is respectively associated with a 5.98% and 0.78% increase in the gap in the per capita housing transaction volume and licensed automobile stock after the referendum
