New solutions to the basic standard New Keynesian model are explored. I extend De Grauwe’s model (2012), distinguishing two types of agents and different expectations rules. The central bank fixes the rate of interest. Families and firms determine aggregated demand and supply. Neither of them...

We document an asymmetry in the rigidity of 9-ending prices relative to non-9-ending prices. Consumers have difficulty noticing higher prices if they are 9-ending, or noticing price-increases if the new prices are 9-ending, because 9-endings are used as a signal for low prices. Price setters...

We show that business cycles can emerge and proliferate endogenously in the economy due to the way economic agents learn, form their expectations, and make decisions regarding savings and production for future periods. There are no exogenous shocks of any kind to productivity or any other...

Can prices convey information about the fundamental value of an asset? This paper considers this problem in relation to the dynamic properties of the fundamental (whether it is constant or time-varying) and the structure of information available to agents. Risk-averse traders receive two...

We analyze in this study what could have caused herding in the stock market. Information cascades have often been considered as a major cause. However, we present in this study evidences inconsistent with that hypothesis. Our analysis is in support of an alternative theory based on search cost...

We analyze in this study cause of herding in a stock market. Information cascades have often been considered as a primary choice. However, we present evidences inconsistent in this study. Employing intraday order book data, our analysis supports the inclusion of of an alternative theory based on...

This paper investigates how trading frictions vary with the thickness of the asset market by examining patterns of asset allocations and prices in commercial aircraft markets. The empirical analysis indicates that assets with a thinner market are less liquid—i.e., more difficult to sell. Thus,...

We attempt to identify in this paper the role of trading noise as a transactions cost to market participant in the sense of Stoll (2000), especially in the presence of trading concentration. Applying the measures of Hu (2006) and Kang and Yeo (2008), we analyze the noise proportion in intraday...

This study sheds new light on the question of whether or not sentiment surveys, and the expectations derived from them, are relevant to forecasting economic growth and stock returns, and whether they contain information that is orthogonal to macroeconomic and financial data. I examine 16...

In this study, we employ a statistical arbitrage approach to demonstrate that momentum investment strategy tend to work better in periods longer than six months, a result different from findings in past literature. Compared with standard parametric tests, the statistical arbitrage method...
