Firms invest heavily in different types of business-to-business relationship marketing activities in the belief that such programs bolster their bottom line. In this study, we develop and test a conceptual model that links customer-specific relationship marketing investments to short-term,...

The two key questions which motivate our work are: do bubbles exist (in the sense that stock market prices do not always correspond to the present value of expected future profitability) and, if bubbles exist, do they have an effect on business fixed investment? The case of Japan is particularly...

We analyze the transaction costs in floor and computerized trading systems. In Germany, floor and screen trading for the same stocks exist in parallel. Bid-ask spreads are not generally lower in one trading system, but the electronic trading system is less attractive for less liquid stocks. This...

In the last twenty years Portugal struggled to keep public finances under control, notably in containing primary spending. We use a new quarterly dataset covering 1979:1-2007:4, and estimate a Bayesian Structural Autoregression model to analyze the macroeconomic effects of fiscal policy. The...

This paper proposes a sequential Monte Carlo method for estimating GARCH models subject to an unknown number of structural breaks. We use particle filtering techniques that allow for fast and efficient updates of posterior quantities and forecasts in real-time. The method conveniently deals with...

This paper characterizes the relationship between entrepreneurial wealth and aggregate investment under adverse selection. Its main finding is that such a relationship need not be monotonic. In particular, three results emerge from the analysis: (i) pooling equilibria, in which investment is...

This paper investigates the behaviour of stock prices in Italy over the 1963-1995 period. By means of a time-series analysis of both the long- and the short-run properties of stock prices and other macroeconomic variables, we find strong evidence of a long-run equilibrium negative relation...

In this paper we provide a brief introduction to the literature on agent-based financial modelling and, more specifically, artificial stock market modelling. In the selective literature review two broad categories of artificial stock market models are discussed: models based on hard-wired rules...

The covariance between US Treasury bond returns and stock returns has moved considerably over time. While it was slightly positive on average in the period 1953--2009, it was unusually high in the early 1980''s and negative in the 2000''s, particularly in the downturns of 2000--02 and 2007--09....

Even though stock returns are not highly autocorrelated, there is a spurious regression bias in predictive regressions for stock returns related to the classic studies of Yule (1926) and Granger and Newbold (1974). Data mining for predictor variables interacts with spurious regression bias. The...
