An immediate consequence of the Efficient Market Hypothesis (EMH) is the absence of auto-correlation of the return series of the financial prices and the exclusion of excess profitability made by any (active) trading strategy. However, the precondition for the validity of EMH, which assumes that...

In many environments, including credit and online markets, past records about participants are collected, published, and erased after some time. We study the effects of erasing past records on trade and welfare in a dynamic market where each seller's quality follows a Markov process and buyers...

In this paper we take into account the role of the banking system, credit and stock market in stimulating aggregate demand in post Keynesian tradition. According to the results of impulse response analysis; it appears all three financial development indicators contributed as expected in...

In the study of economic and financial panel data it is often important to differentiate between time-series and cross-sectional effects. We present two estimation procedures that can do so and illustrate their application by examining international variations in expected equity premia and...

We develop spectral volume models to systematically estimate, explain, and exploit the high-frequency periodicity in intraday trading activities using Fourier analysis. The framework consistently recovers periodicities at specific frequencies in three steps, despite their low signal-to-noise...

In many credit risk and pricing applications, credit transition matrix is modeled by a constant transition probability or generator matrix for Markov processes. Based on empirical evidence, we model rating transition processes as piecewise homogeneous Markov chains with unobserved structural...

We study price determinants and investment performance of art based on a vast sample of transactions around the world over the past 60 years. Art has appreciated at a real (nominal) annual return of 2.49% (6.24%). Higher art returns are reached for paintings at high-end of the price...
