Input–output evidence on the relative price effects of total productivity shift

This paper provides empirical evidence on the relative price effects of a notional shift in total productivity using data from ten Symmetric Input–Output Tables of five European economies. The results suggest that the direction of the price-movements is, more often than not, governed by the (traditional) labour cost condition and this could be connected to the effective ranks of the matrices of the relative shares of the capital goods.     

Dynamic European stock market convergence: Evidence from rolling cointegration analysis in the first euro-decade

The introduction of the euro epitomizes European economic integration. This paper assesses the dynamic process of convergence among four major European stock markets in the first euro-decade. Using tests that allow for endogenously determined breaks in cointegrating relationships and rolling cointegration analysis, we show that although some convergence has been taking place over time, it is very much an ongoing process. There is also evidence that the German and French markets appear to be the ones with a higher degree of convergence while the dominant position of Germany within the eurozone seems to be (re)affirmed by tests conducted herein.     

The fiscal consequences of public health investments in disease-modifying therapies for the treatment of multiple sclerosis in Sweden

Abstract

Background and aims: The economic consequences of multiple sclerosis (MS) are broader than those observed within the health system. The progressive nature suggests that people will not be able to live a normal productive life and will gradually require public benefits to maintain living standards. This study investigates the public economic impact of MS and how investments in disease-modifying therapies (DMTs) influence the lifetime costs to government attributed to changes in lifetime tax revenue and disability benefits based on improved health status linked to delayed disease progression.

Methods: Disease progression rates from previous MS Markov cohort models were applied to interferon beta-1a, peginterferon beta-1a, dimethyl fumarate, and natalizumab using a public economic framework. The established relationship between expanded disability status scale and work-force participation, annual earnings, and disability rates for each DMT were applied. Subsequently, we assessed the effect of DMTs on discounted governmental costs consisting of health service costs, social insurance and disability costs, and changes in lifetime tax revenues.

Results: Fiscal benefits attributed to informal care and community services savings for interferon beta-1a, peginterferon beta-1a, dimethyl fumarate, and natalizumab were SEK340,387, SEK486,837, SEK257,330, and SEK958,852 compared to placebo, respectively. Tax revenue gains linked to changes in lifetime productivity for interferon beta-1a, peginterferon beta-1a, dimethyl fumarate, and natalizumab were estimated to be SEK27,474, SEK39,659, SEK21,661, and SEK75,809, with combined fiscal benefits of cost savings and tax revenue increases of SEK410,039, SEK596,592, SEK326,939, and SEK1,208,023, respectively.

Conclusion: The analysis described here illustrates the broader public economic benefits for government attributed to changes in disease status. The lifetime social insurance transfer costs were highest in non-treated patients, and lower social insurance costs were demonstrated with DMTs. These findings suggest that focusing cost-effectiveness analysis only on health costs will likely underestimate the value of DMTs.     

Local Public Corruption and Bank Lending Activity in the United States

Using a conviction-based measure, we find that local (state-level) public corruption exerts a negative effect on the lending activity of US banks. Our baseline estimations show that the difference in public corruption between, for example, Alabama, where corruption is high, and Minnesota, where corruption is low, implies that banks headquartered in the former state grant 0.55% less credit (or $3.52 million for the average bank) ceteris paribus. Using proxies for relationship lending and monitoring, we also find that these bank characteristics weaken the negative effect of public corruption on lending. These results are robust to tests that address endogeneity, to the use of perception-based measures of corruption, and after controlling for credit demand conditions. In further analysis, we show that these effects are more evident for smaller banks and banks operating in a single state. These findings provide evidence that public corruption could facilitate information asymmetry in the lending market and, thus, could hinder local development by reducing bank credit.

     

The Welfare Consequences of Pollution-Tax Harmonization

A key, and often controversial, issue in environmental negotiations is the appropriate extent of harmonization of environmental policies. This paper, within a general equilibrium model of international trade with endogenous pollution discharges, identifies instances in which pollution-tax harmonization can deliver potential Pareto improvements.     

Hybrid particle swarm optimization with mutation for optimizing industrial product lines: An application to a mixed solution space considering both discrete and continuous design variables

This article presents an artificial intelligence-based solution to the problem of product line optimization. More specifically, we apply a new hybrid particle swarm optimization (PSO) approach to design an optimal industrial product line. PSO is a biologically-inspired optimization framework derived from natural intelligence that exploits simple analogues of collective behavior found in nature, such as bird flocking and fish schooling. All existing product line optimization algorithms in the literature have been so far applied to consumer markets and product attributes that range across some discrete values. Our hybrid PSO algorithm searches for an optimal product line in a large design space which consists of both discrete and continuous design variables. The incorporation of a mutation operator to the standard PSO algorithm significantly improves its performance and enables our mechanism to outperform the state of the art Genetic Algorithm in a simulated study with artificial datasets pertaining to industrial cranes. The proposed approach deals with the problem of handling variables that can take any value from a continuous range and utilizes design variables associated with both product attributes and value-added services. The application of the proposed artificial intelligence framework yields important implications for strategic customer relationship and production management in business-to-business markets.     

Exports,investments and economic development of pre-accession countries of the European Union: an empirical investigation of Bulgaria and Romania

This paper attempts to analyse the relationship between exports, investments and economic development in two pre-accession countries of the European Union, Bulgaria and Romania. For investigation of this relationship a multivariate autoregressive VAR model is used. The results of cointegration analysis showed that there is one cointegrated vector among exports, investments and economic growth for the two countries. Granger causality tests based on error correction models (ECM) indicated that there is a ‘strong Granger causal’ relation between economic growth and exports as well as between investments and exports for the two countries. In addition, economic development and capital accumulation in an economy seem to have just as much of an influence on exports as exports have on capital accumulation and economic development.
