“Equilibrium Bid-Price Dispersion”
Speaker: Albert Menkveld (VU Amsterdam), _https://albertjmenkveld.com/about/ https://albertjmenkveld.com/about/ _
Abstract: If bidding in a common-value auction is costly and if bidders do not know how many others are also bidding, all equilibria are in mixed strategies. Participation is probabilistic and bid prices are dispersed. The symmetric equilibrium is unique and yields simple analytic expressions. We use them to, for example, show that bid prices exhibit negative skewness. The expressions are further used to estimate the model based on bidding on an S&P500 security. We find that the number of bidders declined over time, making liquidity supply fragile.

**Abstract:*Disentangling expectations of future interest rates from risk premia in the determinants of the term structure has long been a challenge, not only to financial economists but to policymakers. Although the great majority of empirical research on the term structure focuses on relatively short maturities (10 years or less), we show that distinguishing between expectations and risk premia is easier at long maturities and, in this paper, we include much longer term rates (20 years and more). In this region, differences in forward rates are little affected by expectations but, nonetheless, reflect significantly differences in risk premia. Key to extracting information about risk premia, is taking proper account of the influence of time-varying volatility of long-term rates and bond convexity. The impact of convexity on the term structure increases strongly with maturity and leads frequently to a negative slope (a “downward tilt”) in long-term forward rates. We employ a four-factor affine model with stochastic volatility that fits the dynamics of the yield curve and, in particular, the downward tilt in forward rates, well. Risk premia in our model are, on average, monotonically upward sloping and we find that volatility accounts for a significant fraction of their variation over time. We also find that including stochastic volatility results in less volatile estimates of term premia than in models with constant volatility. Our model is consistent with previously reported deviations from the pure Expectations Hypothesis, a result which contrasts with previous empirical evidence on the failure of stochastic volatility term structure models in this matter.* * * * *
