Equilibrium reserve prices in sequential ascending auctions

We study a model where bidders have perfectly correlated valuations for two goods sold sequentially in two ascending-price auctions. The seller sets a reserve price before the beginning of each auction. Despite the lack of commitment by the seller, we characterize an equilibrium and study its properties. Strategic non-disclosure of information takes the form of non-participation in the early auction by low-valuation bidders, while high-valuation bidders bid up to their true valuations. Some buyers who would profitably buy at the reserve price refrain from participating in order to decrease the second-auction reserve price.     

It ain’t over till it’s over: A global perspective on the Great Moderation-Great Recession interconnection

A large-scale Factor-Augmented Vector Autoregressive (FAVAR) model of the global economy is used to investigate the determinants of the Great Moderation and the transition to the Great Recession (1986–2010). Beside the global-economy perspective, the model presents the novel feature of a broad range of included financial variables and risk factor measures. The results point to various mechanisms related to the global monetary policy stance (Great Deviation), financial institutions’ risk-taking behaviour (Great Leveraging) and global imbalances (savings glut), determining aggregate fluctuations. Finally, an out-of-sample forecasting exercise provides evidence against the ‘end of the Great Moderation’ view, showing that the timing, though not the dimension of the Great Recession episode (2008–2010), was predictable on the basis of the same macroeconomic mechanisms at work over the two previous decades.     

GARCH inadequacy for modelling exchange rates: empirical evidence from Latin America

This article checks for the adequacy of using GARCH models in exchange rate series. Using the Hinich portmanteau bicorrelation test, we find that a GARCH formulation or any of its variants fails to capture the data generating process of the main Latin American exchange rates. Our results highlight the potential of having misleading public policy when estimates are based in GARCH types of models. This article also complements recent similar findings encountered in European and Asian economies.     

The internal market and hospital efficiency: a stochastic distance function approach

The UK internal market was one of the first European attempts to introduce a competitive mechanism in the provision of hospital services. The assumption was that competition would have led hospitals to increase efficiency in the use of their resources. The aim of this paper is to analyse the effectiveness of this kind of reform by measuring the changes in technical efficiency of a panel of 52 acute Scottish hospitals observed from 1991/92 to 1996/97. The time period covers the whole duration of the internal market and the sample contains a different mix of both trusts and non-trusts, where the former embed the proper working of the reform. The selected model is a stochastic output distance function that includes an interaction dummy variable to allow for parameters to change over time. The results show a structural break after which hospitals change not only the way in which they provide their services, but also the kind of services they provide, favouring the quicker treatment of patients on a day basis. No significant improvement in technical efficiency is detected instead over time, nor any significant difference in efficiency between trusts and non-trusts.     

Portfolio management with tail dependence

Many publications, that treated with Portfolio Management, were devastating for all asset allocation models in the context of portfolios. The elimination of extreme events (asymmetric or tail dependence) during the portfolio construction process can reduce the skills of asset managers to reduce risk through diversification. The copula theory allows us to calculate an alternative to measure the dependence of extreme events in assets through the index lower tail dependence. We check that the strategies with tail dependence overcame Talmud rule, the Markowitz model and the model of Tu and Zhou by simulating 1,000 portfolios with 3, 5, 10 and 20 randomly selected assets from DJIA for the period 03/1990 until 12/2016. We conclude that models of tail dependence and Markowitz had more performance ex-ante than Talmud and the Tu and Zhou model for portfolios with 3, 5, 10 and 20 assets. Tail dependence models overcome Markowitz, in terms of cumulative return, in over 60% of months considered in the analysis. The results indicate that the Talmud rule should be discarded in a context of constructing portfolios with individual stocks ahead strategies with tail dependence.     

International house prices and macroeconomic fluctuations

The paper investigates linkages between general macroeconomic conditions and the housing market for the G-7 area. Among the key results of the paper, we find that the US are an important source of global fluctuations not only for real activity, nominal variables and stock prices, but also for real housing prices. Secondly, albeit distinct driving forces for real activity and financial factors can be pointed out, sizeable global interactions are also evident. In particular, global supply-side shocks are an important determinant of G-7 house prices fluctuations. The linkage between real housing prices and macroeconomic developments is however bidirectional, with investment showing in general a stronger reaction than consumption and output to housing price shocks. Implications for the real effects of the sub-prime crisis are also explored.     

R&D INVESTMENT, CREDIT RATIONING AND SAMPLE SELECTION

We study whether R&D‐intensive firms are liquidity constrained, by modelling their antecedent decision to apply for credit. This sample selection issue is relevant when studying a borrower–lender relationship, as the same factors can influence the decisions of both parties. We find firms with no or low R&D intensity to be less likely to request extra funds. When they do, we observe a higher probability of being denied credit. Such a relationship is not supported by evidence from the R&D‐intensive firms. Thus, our findings lend support to the notion of credit constraints being severe only for a sub‐sample of innovative firms. Furthermore, the results suggest that the way in which the R&D activity is organized may differentially affect a firm's probability of being credit constrained.     

Liquid Applepie: Market Entry Strategy for a New Lifestyle Drink

ABSTRACT

This is a theoretical case which observes the path a small business needs to follow to be successful. It is hoped the company involved will take these conclusions into consideration for future development.

This case study has been conducted in order to understand the theoretical models of international marketing. It determines the key criteria that need to be considered when entering a foreign market. The idea was to develop a market entry strategy for a Polish Vodka manufacturer who wants to enter the Austrian market.

After an analysis of the market and consideration of the situational factors, which are very important for the development of a detailed SWOT analysis, the segmentation, targeting, positioning and finally the selection of the right entry method, including the customer specific marketing tools, have been identified.
