THE 1930s AND THE PRESENT DAY – CRISES COMPARED

Many analysts are comparing the deep crisis of our times with the crash of 1929 and the Great Depression that followed in the 1930s. They generally argue that Barack Obama is driving the world to recovery along Roosevelt's ‘state superiority’ line. Alas, today's crisis rings alarm bells for the manner in which we must manage the future of democracy, the state and markets. Markets cannot be ‘ordered about’ and when in the face of sound logic and practice an attempt is made to do just this, markets become refractory, or – even worse – they may collapse.     

Household food consumption in Turkey: a comment

We comment on a recent important article by Akbay et al. anddiscuss some methodological and estimation issues arising fromtheir paper. We then suggest alternative procedures that mayhelp improve their estimates and thereby enhance their usefulnessas a basis for food policy and marketing decisions.     

ON CONSUMERS' VALUATION OF NUTRITION INFORMATION

The European Union (EU) is contemplating regulations requiring mandatory provision of nutritional information on food products. This study analyses consumers' valuation of nutritional information using data collected from a field survey. The results generally suggest that consumers value and are willing to pay about 5.9 percent of the original price for nutritional information on the food product we studied. Individuals who are non-price-sensitive, nutritionally knowledgeable and with longer time horizon are willing to pay more for nutritional information than others. Considering consumers' willingness to pay for nutritional information on food products and an EU impact assessment study, the costs of provision of this information are not prohibitive to firms. We estimate that the least conservative cost of labelling to the firm for a specific food product can be as much as €29,431, whereas the average economic value of nutrition information is estimated at €17,064. The firm can therefore recoup the associated costs in less than two months.     

Uncertainty in the public debt market and stochastic long-run growth

In a continuous time model, a representative household has to allocate its investment and consumption in an optimal manner under conditions of uncertainty. In the present study it is hypothesized that there are two types of assets: a risk-free and a risky asset. The risk-free asset is assumed to be the physical capital, while at the same time uncertainty is allowed to result from the exogenous random variations in the public debt market, rendering in this way government bonds to act as the risky asset. In the endogenous growth framework with productive public investment, the expected long-run growth rate, the dynamic path of consumption as well as the optimal allocation of investment between a risky and a riskless asset, are analytically derived. This kind of treatment allows us to create a locus for the long-run growth over the various levels of uncertainty. The outcome of the analysis is that a rise in uncertainty impacts negatively upon the long-run growth rate. In order to empirically assess the relationship between growth and uncertainty, we lay our emphasis on the US economy for the period 1957:1 to 2008:4. Within the framework of a bivariate BEKK–GARCH(1,1)-M model a significant negative relationship between uncertainty and economic growth has been established.     

Tourism-led growth asymmetries in Greece: evidence from quantile regression analysis

Portuguese Economic Journal - The paper provides fresh empirical evidence on the tourism-growth relationship for Greece over the period 1977Q1-2020Q2. We find that the long-run relationship between...     

Revising the conventional tax-effort principle

The standard methodology on tax-effort (i.e., the ratio of actual tax revenue to its optimal level) is to run a regression of actual tax revenue on countries’ specific (macroeconomic, demographic, geographical, political, social, and institutional) variables. The resulting predicted (fitted) values are then taken to represent the optimal (desired or maximum) level of tax revenue. The crucial issue of tracing out how the optimal tax revenue should be allocated to the fiscal objectives (equity, efficiency) does not seem to be of any interest to the researchers on tax-effort. The present paper argues that the standard methodology is not without faults and needs revising. We demonstrate that an optimal tax system can be safely derived from maximizing a utility function with respect to (in)direct tax rates. The manipulation of the first-order conditions, using a novel mathematical module, leads to an infinite number of optimal direct–indirect tax rates. The selection of the optimal mix of these tax rates is dependent on the country-specific households’ preferences over equity/efficiency, as they are formulated by voters’ volition in election periods. A simulation procedure helps understanding how the optimal tax revenue is chosen and how it can be optimally allocated to fiscal objectives, in the context of a panel data set including a large number of developed and developing countries. Throughout our text, the optimal tax revenue is defined as the sum of the products of the optimal (in)direct tax rates and their corresponding tax bases. In the simple Arrow–Debreu economy, the above sum is shown to be equal to the difference between income and consumption.     

R &D investments and profitability during the crisis: evidence from Greece

Innovation and Research and Development (R&D) investments have been considered in the literature as a significant determinant of corporate development and sustainability. Previous studies have examined the impact of intangibles on financial performance but not extensively within economic environments of intense financial turmoil. The scope of this study is to shed further light on this issue and examine whether R&D investments had an impact on the profitability of Greek firms especially during the sovereign debt crisis. We collected a sample of Greek corporations that have capitalized their R&D investments and paid significant amounts on R&D expenses during the period 2003–2016. Panel regression results indicated that R&D investments and R&D expenses had a negative impact on the profitability of sample firms before the crisis, but during the crisis (2011–2016) firms which managed to sustain or enhance their level of R&D investments achieved to improve their profitability. These findings corroborate our hypotheses that during a period of limited lending and hearse financial turmoil, R&D investments could be a vital tool for sustaining firms' financial performance. The study offers useful implications for managers and regulators, and contributes to the ongoing debate about the impact of R&D investments on corporate performance.     

The demand for selected nutrients by Greek households: an empirical analysis with quantile regressions

The article uses information from the 1993–1994 Household Consumption Survey and the semiparametric quantile regression approach to analyze the demand for three macronutrients (carbohydrates, proteins, and fats) and three micronutrients (minerals, vitamins, and cholesterol) in Greece. According to the empirical results the age of the household head, the degree of urbanization, the percentage of food expenditure devoted to food away‐from‐home, and the per capita consumption expenditure affect the intakes of nutrients across all the five quantiles considered. The impact, however, of the household head's gender and the impact of his (her) educational achievement are located only at the lower and the higher quantiles, respectively. The expenditure elasticities are substantially lower than unity, suggesting inelastic responses of nutrient intakes to per capita consumption expenditure.     

A synthesis of the production function and the shift-share model : A new regional modelling approach

The purpose of this paper is to suggest a new approach to regional modelling and show the way by which regional expansion paths of output and employment can be developed. Basically, the theoretical model is a synthesis of the production function for the industry (or region), the shift-share model, and a set of hypotheses and a number of identifies concerning the growth components of employment. The growth components of employment specified by the shift-share model and explained by the hypotheses enter and modify the production function in the sense that the shift-share model is linked directly to the production function in which the labor factor appears disaggregated into three distinct components (regional-share, industrial-mix, and national growth component). The theoretical model was tested for the manufacturing industry of the Greek economy. The policy implications of this model center around the fact that policy-makers can affect regional economic variables towards the desired level and direction.
