The output and profit contribution of information technology and advertising investments in banks

This paper examines the contribution of investments in Information Technology (IT) and in advertising to the output and profits of Spanish banks, in the period 1983–2003. We find that the growth in the stock of IT capital explains one third of output growth of banks, and that an additional investment in IT of one million euros may be substituted for twenty-five workers. The paper also finds that advertising investments increase the demand for bank services with an elasticity of 0.22 for deposits and 0.11 for loans. For all the assets considered, the null hypothesis that banks use the profit-maximizing amount of services per period cannot be rejected with the data.     

Government financial statistics and accounting in Europe: is ESA 2010 improving convergence?

This paper provides an empirical analysis of the impact of ESA 2010 on EU member states, looking at countries both individually and as a whole and analysing the global impact of the adjustments and the partial impacts of each category. Changing the system of national accounts has introduced conceptual and methodological changes, but there has not been any significant variation in the convergence/divergence between government financial statistics and budgetary accounting in reporting deficits. The effect on the deficits reported by individual member states was quite marked however.     

Amino acid formula as a new strategy for diagnosing cow’s milk allergy in infants: is it cost-effective?

Aims: To estimate the cost-effectiveness of a new strategy that uses an amino acid formula in the elimination diet of infants with suspected cow’s milk allergy (CMA).

Materials and methods: This pharmacoeconomic study was developed from the perspective of the Brazilian Public Healthcare System. The new strategy proposes using an amino acid formula in the diagnostic elimination diet of infants (≤24 months) with suspected CMA. The rationale is that infants who do not respond to the amino acid formula do not suffer from CMA. Patients with a positive oral challenge test receive a therapeutic elimination diet based on Brazilian Food Allergy Guidelines. This approach was compared to the current recommendations of the Brazilian Food Allergy Guidelines. A decision model was constructed using TreeAge Pro 2012 software. Model inputs were based on a literature review and the opinions of a panel of experts. A univariate sensitivity analysis of incremental cost-effectiveness ratios was performed.

Results: The mean cost per patient of the new amino acid formula strategy was R$3,341.57, while the cost of the current Brazilian guidelines strategy was R$3,641.08. The mean number of symptom-free days per patient, which was used as an indicator of effectiveness, was 900.6 and 875.7 days, respectively. The new strategy is, therefore, dominant. In the sensitivity analysis, the dominance was maintained with parameter variation.

Limitations: In the absence of information in the literature, some premises were defined by a panel of specialists.

Conclusions: The new strategy, which uses an amino acid formula in the elimination diagnostic diet followed by an oral food challenge, is a dominant pharmacoeconomic approach that has a lower cost and results in an increased number of symptom-free days.     

IS E‐GOVERNMENT LEADING TO MORE ACCOUNTABLE AND TRANSPARENT LOCAL GOVERNMENTS? AN OVERALL VIEW

This paper seeks to assess to what extent e-government enables accountability and transparency in EU local governments. It also provides an overall view about how local governments are implementing ICTs initiatives to bring citizens closer to governments. Although the mere capacity of the Internet for the dissemination of information improves accountability and makes benchmarking easier, our results show that the expected benefits are far from being achieved because e-government projects are still in the early stages. The results also show that, at present, ICTs have not had a dramatic impact on EU local government accountability.     

Is it punishment? Sovereign defaults and the decline in trade

Sovereign defaults are associated with declines in defaulting countries trade. Are these declines the result of trade sanctions as the trade sanctions argument of sovereign borrowing would suggest? We devise an empirical strategy to evaluate this issue based on the idea that if trade sanctions are causing the declines, bilateral trade with creditor countries should fall more than trade with other countries. We find that this is not the case. The analysis does not yield much evidence of broader punishment strategies including a league of major creditors either. These results contradict the predictions of the trade sanctions theory of sovereign borrowing.     

Information Gathering Externalities for a Multi‐Attribute Good

Most goods and services vary in numerous dimensions. Customers choose to acquire information to assess some characteristics and not others. Their choices affect firms' incentives to invest in quality and so lead to indirect externalities in consumers' choices. We characterize a model in which a monopolist invests in the quality of a product with two characteristics, and consumers are heterogeneous ex‐ante. Consumers do not internalize their influence on the firm's investment incentives when choosing which information to acquire. Cheaper information affects consumers' information gathering and thereby firm investment. This can paradoxically reduce consumer surplus, profits, and welfare.     

Loving Outside the Neighborhood: The Conflicting Effects of External Linkages on Incremental Innovation in Clusters

The present study assesses the explanatory capacity of three levels of factors, namely, internal to the company, and internal and external to the cluster, in predicting firms' incremental innovative performance in cluster contexts. The empirical research conducted here focuses on a sample of 92 companies from the Spanish textile industrial cluster in Valencia. Findings reveal that the significant role played by firms' interorganizational ties as a moderating factor between absorptive capacity and their incremental innovative performance. Additionally, results reflect the differentiated roles developed by intra‐ and extra‐cluster linkages in these interaction processes.

A Cointegration Analysis of Car Advertising and Sales Data in the Presence of Structural Change

This paper examines whether there is a long‐run stable equilibrium relationship between advertising and sales across the market segments of the UK car industry over the period 1971–2001. In order to achieve this goal, we allow for structural breaks in the series using cointegration techniques. The results show the existence of long‐run equilibrium relationships in all six market segments, although in four of them the relationship is not stable. In general, one structural change is detected in the late 1970s and another in the early 1990s, coinciding with two economic recessions. When we do not account for structural changes, the estimated long‐run elasticities of advertising on sales are seen to be substantially downwardly biased. Finally, a noticeable increase is observed in long‐run elasticities in most car market segments during the nineties with respect to previous decades.     

Learning about monetary policy rules when the cost-channel matters

We study how monetary policy may affect determinacy and expectational stability (E-stability) of rational expectations equilibrium when the cost channel of monetary policy matters. Focusing on instrumental Taylor-type rules and optimal target rules, we show that standard policies can induce indeterminacy and expectational instability when the cost channel is present. A naïve application of the traditional Taylor principle could be misleading, and expectations-based reaction function under discretion does not always induce determinate and E-stable equilibrium. This result contrasts with the findings of Bullard and Mitra [2002. Learning about monetary policy rules. Journal of Monetary Economics 49, 1105–1129] and Evans and Honkapohja [2003. Expectations and stability problem for optimal monetary policies. Review of Economic Studies 70, 807–824] for the standard new Keynesian model. The ability of the central bank to commit to an optimal policy is an antidote to these problems.
