Average stock price reactions of industry peers in horizontal foreign acquisitions around deal announcements are significantly negative. The stock price effects increase with relatively high market-to-book ratio peers, with larger acquirers, and with the differences in industry specialization...

Empirical reports of priced foreign exchange (FX) risk raise the question of whether managers should adjust their cost of equity estimates for FX risk. To study this question, we empirically compare the cost of equity estimates of several risk-return models, including some that have explicit FX...

This paper investigates mispricing (specifically limits to arbitrage) as an alternative to the risk-based explanation of the globalization premium documented by Barrot et al. (2019). We document that the globalization premium is positively correlated with measures of limits to arbitrage. We...

This thesis comprises four papers concerning modelling of financial count data. Paper [1], [2] <p> and [3] advance the integer-valued moving average model (INMA), a special case of integer-valued <p> autoregressive moving average (INARMA) model class, and apply the models to the number of <p> stock...</p></p></p>

The paper considers conditional duration models in which durations are in continuous time but measured in grouped or discretized form. This feature of recorded durations in combination with a frequently traded stock is expected to negatively influence the performance of conventional estimators....

This thesis comprises four papers concerning trade durations and limit order book information. Paper [1], [2] and [4] study trader durations, e.g., the time between stock transactions in intra-day data. Paper [3] focus on the information content in the limit order book concerning future price...

This thesis comprises two papers concerning modelling of financial count data. The papers advance the integer-valued moving average model (INMA), a special case of integer-valued autoregressive moving average (INARMA) model class, and apply the models to the number of stock transactions in...

A vector integer-valued moving average (VINMA) model is introduced. <p> The VINMA model allows for both positive and negative correlations <p> between the counts. The conditional and unconditional first and second <p> order moments are obtained. The CLS and FGLS estimators are discussed. <p> The model is...</p></p></p></p>

The integer-valued moving average model is advanced to model the number of transactions in intra-day data of stocks. The conditional mean and variance properties are discussed and model extensions to include, e.g., explanatory variables are offered. Least squares and generalized method of moment...

A bivariate integer-valued moving average (BINMA) model is proposed. The BINMA model allows for both positive and negative correlation between the counts. This model can be seen as an inverse of the conditional duration model in the sense that short durations in a time interval correspond to a...
