Speculative attacks to currency target zones: A market microstructure approach

This paper develops a simple optimization model to characterize the behaviour of market participants during currency attacks and tests it empirically. Specifically, we test for the determinants of the timing, magnitude and chance of success of an attack. The empirical part is carried out using Mexican data, as this market provides us with an appropriate target zone framework and with a very rich dataset. We find empirical support for a set of microeconomic determinants which include: daily order flow, inventory management, intra-day price volatility, and the forward intervention-price differential. Finally, we test for the role of central bank reserves in speculative attack dynamics.     

Regime-switching and interest rates in the European monetary system

This paper examines the impact that a currency target zone has on short-term interest rates. For a number of countries in the European Monetary System, we characterize the short rate using a regime-switching model that allows for a differently parameterized mean-reverting square-root process in each regime. We find that the volatility, the level, and the speed-of-adjustment are all higher in the regime that is operative during speculative attacks and currency crises. Moreover, we allow the conditional probability of being in each regime to be state-dependent so the model can be used to examine questions relating to the likelihood of realignments and the stability of the target zone system.

How and why auditors’ social exchange relationships influence their attitudes and behaviors: Implications for audit quality

External auditors regularly interact with various parties at work, such as their accounting firms, engagement team members, and clients. These interactions can help shape the nature of auditors’ social exchange relationships with these entities, which in turn may influence their behavior toward these targets. This installment of Accounting Matters draws from recently published research by Herda and colleagues to (1) explain how constructive auditor-target connections can develop and lead to beneficial outcomes like reduced auditor burnout and turnover intentions, as well as more citizenship behavior, and (2) discuss how these upshots might ultimately affect audit quality. This topic is important because audit quality translates into improved financial reporting, which helps stakeholders who rely on audited financial statements to make informed business decisions. Specifically, we underscore the key role auditors’ perceptions of fair treatment from a relationship partner play in fostering a strong psychological bond with the target via perceived support. We further consider how auditors’ consequent commitment to the target can result in favorable organizational outcomes, including enhanced audit and financial reporting quality. We also discuss practical implications for accounting firms.     

Optimal targeting of latent tourism demand segments

This paper identifies for the first time the optimal target markets employing the latent tourism demand expenditure, a novel concept in tourism literature. The study quantifies latent tourism demand between each pair of origin-destination through distinguishing by type of tourism and seasonality. It works with market shares that are estimated via a fractional regression model. Moreover, latent demand is clustered using a market segmentation approach based on a latent class regression. Finally, the optimal target markets are chosen depending on the expected latent tourism expenditure. The result has clear policy implications in terms of which markets are promoted, the optimal channels of communication and the maximum budget for each marketing campaign.     

Incorporating active adjustment into a financing based model of capital structure

The conventional partial adjustment model, which focuses on leverage evolution, has difficulty identifying deliberate capital structure adjustments as it confounds financing decisions with the mechanical autocorrelation of leverage. We propose and estimate a financing-based partial adjustment model that separates the effects of financing decisions on leverage evolution from mechanical evolution. The speed of adjustment (SOA) is firm-specific and stochastic, and active targeting of capital structure has a multiplier effect that depends on the size of financial deficit. Overall, we find expected SOA from active rebalancing (30%) more than doubles what is expected from mechanical mean reversion alone (13%).     

Deal characteristics and M&A performance: How do hospitality firms fare?

The global hospitality industry has experienced significant consolidation in the past several decades. While evidence in the general business literature suggests that the target firm shareholders gain instead of the acquiring firm shareholders, some studies in the hospitality industry have suggested that mergers and acquisitions (M&As) are also beneficial to acquiring firms. Using a comparative study design and a comprehensive sample over 41 years, we empirically examine whether M&As create more value in the hospitality industry than in other industries and whether certain deal characteristics may explain the potential performance differential. Overall, we find that M&As in the hospitality industry outperform M&As in non-hospitality sectors. When examining deal attributes, we find that relative size of target, cash method of payment, and an unlisted target are characteristics positively related to merger performance and help explain some of the performance differential. We contribute theoretically and empirically to the literature by demonstrating that industry and deal effects play an important role in M&A performance.
