Social orders,and a <Emphasis Type="Italic">weak</Emphasis> form of the Hayek–Friedman Hypothesis

This paper contributes to a theoretical underpinning of the economic freedom–political freedom relationship. We use the theory of social orders (North et al. in Violence and social orders: a conceptual framework for understanding recorded human history, Cambridge University Press, Cambridge, 2009) to look at the Hayek–Friedman Hypothesis (HFH), which leads us to propose a novel interpretation. The core insight of our weak interpretation of the hypothesis is that economic freedom is a necessary condition for maintaining political freedom in open access order countries (countries with high levels of both freedoms), i.e., once achieved, political freedom needs economic freedom to be stable; but the HFH is not relevant for limited access orders (rent-seeking-dominated orders). We find empirical support for the weak interpretation with canonical correlations and conditional logit regressions, using a panel database for 122 countries for the period 1980–2011.     

Purchasing power parity for G-7 countries: panel SURADF tests

In this study, the panel Seemingly Unrelated Regressions Augmented Dickey–Fuller (SURADF) tests advanced by Breuer et al. (2001 Breuer, J. B., McNown, R. and Wallace, M. S. 2001. Misleading inferences from panel unit-root tests with an illustration from purchasing power parity. Review of International Economics, 9: 482–93. [Crossref] , [Google Scholar]) are used to test the validity of Purchasing Power Parity (PPP) for G-7 countries over the period 1980M1 to 2008M5. The empirical results from several panel-based unit root tests indicate that PPP does not hold for G-7 countries under study; however, Breuer et al.'s (2001 Breuer, J. B., McNown, R. and Wallace, M. S. 2001. Misleading inferences from panel unit-root tests with an illustration from purchasing power parity. Review of International Economics, 9: 482–93. [Crossref] , [Google Scholar]) panel SURADF tests unequivocally indicate that PPP is valid for half of the G-7 countries.     

The Causal Relationship between Economic Policy Uncertainty and Stock Market: A Panel Data Analysis

This study applies recently developed bootstrap panel Granger causality, proposed by Kónya, to investigate a causal link between economic policy uncertainty and stock markets in nine countries over monthly periods from 2003M01 to 2014M12 (Kónya (2006 Kónya, L. (2006). Exports and growth: Granger causality analysis on OECD countries with a panel data approach. Economic Modelling, 23, 978–992. doi: 10.1016/j.econmod.2006.04.008[Crossref], [Web of Science ®] , [Google Scholar]) Exports and growth: Granger causality analysis on OECD countries with a panel data approach. Economic Modelling, 23, 978–992). The modeling allows us to examine both the cross-sectional dependency and the country-specific heterogeneity. The empirical results indicate that not all countries are alike, and that the theoretical prediction that stock markets fall at the announcement of a policy change is not always supported. Specifically, this work finds evidence of the stock market leading hypothesis for India, Italy, and Spain, while the economic policy uncertainty leading hypothesis cannot be rejected for the United Kingdom. In addition, the neutrality hypothesis was supported in the remaining countries (Canada, China, France, Germany and the United States), while the feedback hypothesis, however, is not found. The findings of this study could provide important policy implications for these nine countries.     

Long-run purchasing power parity and asymmetric adjustment in BRICs

The primary aim of this study is an attempt to determine whether the Purchasing Power Parity (PPP) hypothesis holds for those countries that have collectively come to be known as ‘BRICs’, namely, Brazil, Russia, India and China. We use the momentum threshold cointegration tests (advanced by Enders and Siklos, 2001 Enders, W. and Siklos, P. L. 2001. Cointegration and threshold adjustment. Journal of Business Economics and Statistics, 19: 166–76. [Taylor & Francis Online], [Web of Science ®] , [Google Scholar]) to investigate whether any asymmetric adjustment is discernible for BRICs, and show that whilst the Engle–Granger test (which assumes only symmetric adjustment) fails to reveal any cointegrational relationship for BRICs, the threshold cointegration test (with asymmetric adjustment) provides clear evidence of long-run PPP for BRICs, with the notable exception of China. We conclude that asymmetric adjustment of nominal exchange rates plays an important role in eliminating deviations from long-run PPP.     

The relationship between population growth and standard-of-living growth over 1870–2013: evidence from a bootstrapped panel Granger causality test

This paper examines the linkages between population growth and standard-of-living growth in 21 countries over the period of 1870–2013. We apply the bootstrap panel causality test proposed by Kónya (Econ Model 23:978–992, 2006), which accounts for both dependency and heterogeneity across countries. We find one-way Granger causality running from population growth to standard-of-living growth for Finland, France, Portugal, and Sweden, one-way Granger causality running from standard-of-living growth to population growth for Canada, Germany, Japan, Norway and Switzerland, two-way causality for Austria and Italy, and no causal relationship for Belgium, Brazil, Denmark, Netherlands, New Zealand, Spain, Sri Lanka, the UK, the USA, and Uruguay. Dividing the sample into two subsamples due to a structural break yields different results over the two periods of 1871–1951 and 1952–2013. Our empirical results suggest important policy implications for these 21 countries as the directions of causality differ across countries and time period.     

Revisiting purchasing power parity for major OPEC countries: evidence based on nonlinear panel unit-root tests

In this study, we apply nonlinear panel unit-root test to assess the nonstationary properties of the real exchange rate for seven major Organization of the Petroleum Exporting Countries (OPEC). We find that nonlinear panel unit-root test has higher power than linear method suggested by Breuer et al. (2001 Breuer, J. B., McNown, R. and Wallace, M. S. 2001. Misleading inferences from panel unit-root tests with an illustration from purchasing power parity. Review of International Economics, 9: 482–93. [Crossref] , [Google Scholar]) if the true data generating process of exchange rate is in fact a stationary nonlinear process. We re-examine the validity of Purchasing Power Parity (PPP) from the panel nonlinear point of view and provide robust evidence clearly indicating that PPP holds true for four countries, namely Angola, Indonesia, Iran and Saudi Arabia. Our findings point out their exchange rate adjustment is mean reversion towards PPP equilibrium values in a nonlinear way.     

Using simulation experiments to test historical explanations: the development of the German dye industry 1857-1913

In a simulation experiment, building on the abductive simulation approach of Brenner and Werker (2007), we test historical explanations for why German firms came to surpass British and France firms and to dominate the global synthetic dye industry for three decades before World War 1 while the U.S. never achieved large market share despite large home demand. Murmann and Homburg (J Evol Econ 11(2):177–205, 2001) and Murmann (2003) argued that German firms came to dominate the global industry because of (1) the high initial number of chemists in Germany at the start of the industry in 1857, (2) the high responsiveness of the German university system and (3) the late (1877) introduction of a patent regime in Germany as well as the more narrow construction of this regime compared to Britain, France and the U.S. We test the validity of these three potential explanations with the help of simulation experiments. The experiments show that the 2nd explanation—the high responsiveness of the German university system— is the most compelling one because unlike the other two it is true for virtually all plausible historical settings.     

A Model of U.K. Exports of Manufactures to Industrial Countries

THIS paper describes a model of U.K. exports of manufactures to industrial countries. The model is outlined in the first section and estimated in the succeeding section. The next section compares the relative efficiencies of aggregate and micro-relations. The paper ends with a discussion of a partially reduced form of the model.

Industrial countries are defined as 1967 OECD members (excluding Iceland); ¹ 1. That is: Canada, U.S.A., Austria, Belgium-Luxembourg, Denmark, France, Germany, Greece, Ireland, Italy, Japan. Netherlands, Norway, Portugal, Spain, Sweden, Switzerland, Turkey, and the U.K. This definition thus includes some countries often classified as ‘semi-industrial’. these countries accounted for 50 per cent of world imports of manufactures and 70 per cent of total world imports and took about 56 per cent of U.K. total exports of manufactures, in 1967. Manufactured goods are defined as SITC Sections 5–8 inclusive. Quarterly data from 1956 to mid-1968 are used. All trade and price series are expressed at 1963 U.S. dollar prices, and activity indicators are also expressed in real terms. This was because it was thought that the structural parameters of the model could be better estimated using volume rather than value flows. Also the full London Business School macro-economic model measures national income as the sum of expenditures corresponding to output produced at home at 1963 prices. So, in forecasting G.D.P., estimates are needed of U.K. exports at 1963 prices. Conversion to current price forecasts, for balance of payments purposes, is made using an explanatory relationship for U.K. export prices of manufactures. Conversion into sterling terms from dollar values is straightforward, after allowing for the sterling devaluation of November, 1967.

The present model is only a partial version of a larger system explaining individual trade flows between countries; it is concerned only with indiliidual relations for British exports by markets and with total import flows for the other industrial countries.     

How do middle-aged children allocate time and money transfers to their older parents in Europe?

This paper analyses the determinants of financial and time transfers from adult children to their older parents using the Survey of Health, Ageing and Retirement in Europe (SHARE). It is the first survey containing rich comparable interdisciplinary information about individuals aged 50+ from ten European countries (Austria, Denmark, France, Germany, Greece, Italy, the Netherlands, Spain, Sweden and Switzerland). The first part of the paper highlights the differences in the provision of upward private intergenerational transfers (in terms of both time and money) across the ten European countries. The second part describes the different determinants in the decision to provide time or money transfers to parents and evaluates whether these two types of assistance are substitutes or complements. Results highlight the existence of a substitution between time and money in relation to geographical distance and the existence of a weak substitution regarding the employment status of the middle-aged children.

Examining world-wide purchasing power parity

We examine long-run PPP between Germany, Great Britain, Japan and the United States over the period 1930–1996 using multivariate cointegration techniques. Bilateral PPP between the four countries is examined in one system (as opposed to e.g. series of trivariate systems). In all of the statistical analysis, asymptotic tests are augmented by parametric bootstrap analogues, whereby we reduce, if not eliminate, the size distortion typically present in small-sample studies. The cointegration analysis provides support for the necessary conditions for PPP (i.e. cointegrating relations are found) but not for the sufficient conditions (i.e., the coefficients in the cointegrating relations are far from what PPP predicts). These results are at odds with results from other studies that also analyze long-horizon data sets.First version received: November 2000/Final version received: February 2003Comments by Stefan Norrbin, Lee Ohanian, Anders Vredin, seminar-participants at Sveriges Riksbank (the central bank of Sweden) and at the Econometric Society European Meeting in Santiago de Compostela are gratefully acknowledged.     

Cost and economic burden of adverse events associated with metastatic melanoma treatments in five countries

Objective: To estimate per-event cost and economic burden associated with managing the most common and/or severe metastatic melanoma (MM) treatment-related adverse events (AEs) in Australia, France, Germany, Italy, and the UK.

Methods: AEs associated with chemotherapy (dacarbazine, paclitaxel, fotemustine), immunotherapy (ipilimumab), and targeted therapy (vemurafenib) were identified by literature review. Medical resource use data associated with managing AEs were collected through two blinded Delphi panel cycles in each of the five countries. Published costs were used to estimate per-event costs and combined with AEs incidence, treatment usage, and MM prevalence to estimate the economic burden for each country.

Results: The costliest AEs were grade 3/4 events due to immunotherapy (Australia/France: colitis; UK: diarrhea) and chemotherapy (Germany/Italy: neutropenia/leukopenia). Treatment of AEs specific to chemotherapy (Australia/Germany/Italy/France: neutropenia/leukopenia) and targeted therapy (UK: squamous cell carcinoma) contributed heavily to country-specific economic burden.

Limitations: Economic burden was estimated assuming that each patient experienced an AE only once. In addition, the context of settings was heterogeneous and the number of Delphi panel experts was limited.

Conclusions: Management costs for MM treatment-associated AEs can be substantial. Results could be incorporated in economic models that support reimbursement dossiers. With the availability of newer treatments, establishment of a baseline measure of the economic burden of AEs will be crucial for assessing their impact on patients and regional healthcare systems.     

Economic impact of onabotulinumtoxinA for overactive bladder with urinary incontinence in Europe

Background: Overactive bladder (OAB) is a common condition that has a significant impact on patients’ health-related quality-of-life and is associated with a substantial economic burden to healthcare systems. OnabotulinumtoxinA has a well-established efficacy and safety profile as a treatment for OAB; however, the economic impact of using onabotulinumtoxinA has not been well described.

Methods: An economic model was developed to assess the budget impact associated with OAB treatment in France, Germany, Italy, Spain and the UK, using onabotulinumtoxinA alongside best supportive care (BSC)—comprising incontinence pads and/or anticholinergic use and/or clean intermittent catheterisation (CIC)—vs BSC alone. The model time horizon spanned 5 years, and included direct costs associated with treatment, BSC, and adverse events.

Results: Per 100,000 patients in each country, the use of onabotulinumtoxinA resulted in estimated cost savings of €97,200 (Italy), €71,580 (Spain), and €19,710 (UK), and cost increases of €23,840 in France and €284,760 in Germany, largely due to day-case and inpatient administration, respectively. Projecting these results to the population of individuals aged 18 years and above gave national budget saving estimates of €9,924,790, €27,458,290, and €48,270,760, for the UK, Spain, and Italy, respectively, compared to cost increases of €12,160,020 and €196,086,530 for France and Germany, respectively. Anticholinergic treatment and incontinence pads were the largest contributors to overall spending on OAB management when onabotulinumtoxinA use was not increased, and remained so in four of five scenarios where onabotulinumtoxinA use was increased. This decreased resource use was equivalent to cost offsets ranging from €106,110 to €176,600 per 100,000 population.

Conclusions: In three of five countries investigated, the use of onabotulinumtoxinA, in addition to BSC, was shown to result in healthcare budget cost savings over 5 years. Scenario analyses showed increased costs in Germany and France were largely attributable to the treatment setting rather than onabotulinumtoxinA acquisition costs.     

Purchasing power parity for East-Asia countries: further evidence based on panel stationary test with multiple structural breaks

In this article, we re-investigate the validity of Purchasing Power Parity (PPP) for a sample of 10 East-Asia countries over the period of January 1987 to June 2005, using a recently developed econometric technique of the panel stationary test with multiple structural breaks, proposed by Carrion-i-Silvestre et al. (2005 Carrion-i-Silvestre, JL, Del Barrio, T and López-Bazo, E. 2005. Breaking the panels: an application to the GDP per capita. Econometrics Journal, 8: 159–75. [Crossref], [Web of Science ®] , [Google Scholar]). This test considers multiple structural breaks positioned at different unknown dates and a different number of breaks for each individual. Empirical evidence shows that the PPP holds true for half of 10 East-Asia countries during the research period. Our results have important policy implications for these 10 East-Asia countries under study.     

Temporal risk and the nature of induced preferences

It has been known since the work of H. Markowitz (“Portfolio Selection: Efficient Diversification of Investments,” Yale Univ. Press, 1959) and J. Mossin (Amer. Econ. Rev.59 (1969), 172–174) that even an individual whose underlying preferences satisfy the von Neumann-Morgenstern axioms will not choose over delayed (i.e., “temporal”) risky prospects in a manner which can be modelled as expected utility maximizing. Since most economically important instances of risk taking (insurance, real investment, agriculture, career training) involve delayed as opposed to immediately resolved risk, the standard use of expected utility theory to model such decisions must be questioned. In this paper the technique of “generalized expected utility analysis” (M. J. Machina, Econometrica50 (1982), 277–323) and the theory of support functions (R. T. Rockafellar, “Convex Analysis,” Princeton Univ. Press, 1970) are applied to exactly model and hence determine the nature of preferences over temporal risky prospects.     

PPP in the 34 OECD countries: evidence from quantile-based unit root tests with both smooth and sharp breaks

Conventional unit root tests have mostly failed to validate the PPP. Quantile-based unit root tests by previous research have provided some support for the PPP. In this article, we take an additional step and incorporate sharp shifts and smooth breaks into the quantile-based unit root test and re-examine the PPP in each of the 34 OECD countries over the period 1994:01–2016:03. We find support for the PPP in 18 countries of Austria, Chile, Estonia, Finland, France, Germany, Italy, Korea, Mexico, Netherlands, New Zealand, Poland, Portugal, Slovenia, Sweden, Switzerland, Turkey and the United Kingdom.     

Modelling lifetime cost consequences of toric compared with standard IOLs in cataract surgery of astigmatic patients in four European countries

Abstract

Objective: To compare the lifetime costs of freeing astigmatic patients from spectacles after bilateral cataract surgery implanting toric intraocular lenses (IOLs: i.e., Acrysof Toric) versus monofocal IOLs, in France, Italy, Germany and Spain.

Methods: A Markov model followed patient cohorts from cataract surgery until death. Prevalence rates of patients not needing spectacles and the types of spectacles prescribed for those requiring them were obtained from clinical trials and national surveys. The economic perspective was societal. Mortality rates were incorporated into the model. Discount rates were applied. A sensitivity analysis was performed on non-discounted costs.

Results: Fewer patients with toric IOLs needed spectacles for distance vision than patients with monofocal IOLs. With monofocal IOLs more than 66% of patients needed complex spectacles compared to less than 25% implanted with toric IOLs. In France and Italy, toric IOLs reduced overall costs relative to otherwise high spectacle costs after cataract surgery. Savings were €897.0 (France), €822.5 (Germany), €895.8 (Italy) and €391.6 (Spain), without discounting. On applying a 3% discount rate the costs became €691.7, €646.4, €693.9 and €308.2, respectively.

Conclusions: Bilateral toric IOL implants in astigmatic patients decreased spectacle dependence for distance vision and the need for complex spectacles. The economic consequences for patients depended on the national spectacle costs usually incurred after cataract surgery.     

Growth in India’s Service Sector: Implications of Structural Breaks

The paper is an attempt to identify the multiple structural breaks in India’s GDP, as well as its main growth enhancing sector i.e., services and its components and subsequently calculate the growth rate in different regimes. The paper uses the Bai-Perron (Econom 66(1), 1998, J Appl Econom 18(1), 2003) methodology of estimating multiple endogenous structural breaks (both pure and partial) in India’s service sector and its components and GDP during 1950–2010. Further, the paper uses the Boyce (Oxf Bull Econ Stat 48:385–391, 1986) methodology of estimating kinked exponential model of the growth rate, and further uses the Banerjee, Lumsdaine and Stock (J Business Econ Stat 10:271–287, 1992) test and the Lumsdaine and Pappel (Rev Econ Stat 79:212–218, 1997) test to check for the stationarity in the presence of structural breaks. The data used in this paper are the components of subsectors of services GDP and GDP at factor cost (with 2004–2005 as base). It is found that there is very little difference between the estimation of pure and partial structural break dates in India’s services GDP and its subsectors and four such breaks have been identified with help of Bai-Perron (Econom 66(1), 1998, J Appl Econom 18(1), 2003) methodology. The Boyce methodology of estimation of growth rates finds that mainly in the third and fourth regimes, the growth rates are highest in the subsectoral as well as at the aggregate levels of services GDP. The Banerjee, Lumsdaine and Stock test (J Business Econ Stat 10:271–287, 1992) and the extended Lumsdaine and Pappel test (Rev Econ Stat 79:212–218, 1997) cannot negate the presence of unit root in the data, irrespective of the presence of multiple structural breaks. The paper concludes with the identification of four broad regimes of growth of India’s services GDP and in the subsectors with possible explanations thereof.

     

Is the Engel curve approach viable in the estimation of alternative PPPs?

Conventional estimates of purchasing power parities (PPP) rely on cross-country price data. Using Engel curves, Almås (Am Econ Rev 102:1093–1117, 2012) was, however, able to show that PPPs contain substantial bias. Since constructing conventional estimates is expensive and time consuming, Almås’ idea of employing Engel curves is welcome. This article examines the viability of the Engel curve approach to PPP and its sensitivity to differences in relative prices and preferences by estimating Engel curves not only between countries but also for regions within a given country. My empirical evidence from the United States and Norway suggests that the differences can be problematic, but not sufficiently to discredit the new methodology. A pragmatic approach to PPP estimation between countries that are different is to compute a PPP band, rather than a point estimate. I present a practical example of this using expenditure data from 2001, which yields a band for NOK and US dollar.     

Germany and Italy: conflicting policy paradigms towards European monetary integration?

In the literature on European monetary integration Germany and Italy are mostly strongly contrasted. However, this paper argues that there were important similarities between the policy paradigms in these two countries, in particular if a broader historical perspective is adopted. This work analyses the policy paradigms towards European monetary integration in Italy and Germany. Moreover, it contextualises these paradigms into the national institutional setting: while Germany was characterised by power sharing institutions, Italy featured power fragmentation (something which also affected the economic performance of both countries). There were significant differences between the policy paradigms of foreign policy-makers and economic policy-makers. Foreign policy makers, in both countries, under the influence of a European federalist vision, were strongly in favour of European monetary integration. These beliefs of foreign policy decision makers were crucial in charting EMU policy at history-making moments. The pro EMU policy paradigms of foreign policymakers contrasted, during most of the period covered, with the more sceptical beliefs of economic policy makers. In both countries, economic policy-makers, at different moments, had doubts whether enough “convergence” had been reached to make a more stable exchange rate system sustainable.

Supportability and anonymous equity

W. W. Sharkey and L. G. Telser (J. Econom. Theory18 (1978), 23–37) feel that invulnerability of a natural monopoly to the threat of competitive entry is well reflected in the concept of supportability. G. R. Faulhaber and S. B. Levinson (Amer. Econom. Rev.71 (1981), 1083–1091) point out that supportability is necessary for the achievability of anonymous equity, i.e., absence of consumer subsidies in public enterprise pricing. This paper reconciles supportability with market clearance and shows that supportability is sufficient for the achievability of anonymous equity.
