More health care utilization with more insurance coverage? Evidence from a latent class model with German data

We analyse the impact of optional deductibles, private supplementary health insurance and income on the demand for health care utilization, measured as the number of physician visits with data from the German Socio-Economic Panel (SOEP). With a set of newly available variables for the years 2002, 2004 and 2006 that measure individual health more accurately and including risk-attitudes towards health we find that possible endogeneity of the insurance choice is not a problem. A latent class approach that takes into account the panel structure of the data reveals that especially individuals who have few doctor visits, the low users, respond strongest to insurance status and income. In this group we find that more insurance increases the demand for physician visits and there is a pro-rich inequity in health care utilization. No such effects are found for the high users.     

Do cash flow imbalances facilitate leverage adjustments of Chinese listed firms? Evidence from a dynamic panel threshold model

This paper investigates the asymmetric impact of cash flow on firms’ leverage adjustments. We use a dynamic panel threshold model and estimate it with a newly-developed first-difference GMM approach, which allows endogeneity in both threshold variable and regressors. Employing data of 1054 Chinese listed firms during 2004–2016, we show that Chinese listed firms have leverage targets, towards which they adjust at an average speed of 25.9%. Moreover, firms with larger absolute cash flow adjust towards their leverage targets significantly faster than those with smaller absolute cash flow. This finding is robust to a post-financial crisis sample period, alternative measures of leverage and cash flow, and the incorporation of an additional control variable. We find evidence that cash flow imbalances facilitate leverage adjustments by reducing adjustment costs, and Chinese listed firms rely more on debt issues. These findings provide new insights on firms’ leverage adjustment and cash flow management.     

After work shopping? Employment effects of a deregulation of shop opening hours in the German retail sector

This study investigates the impact of a deregulation of shop opening laws on employment in the German retail sector. Exploiting the gradual change in the opening times of shops across states and using data from the German Socio-Economic Panel, difference-in-differences estimates indicate an average increase in the employment probability, driven by a rise in the likelihood of working marginal part-time hours. Workers in small firms are likely to experience a reduction of their propensity to work. For individuals facing high family-related, supply-side constraints, the change in shop opening hours has opposing effects on employment — positive on lower and negative on upper parts of the hours distribution. Overall, the deregulation is estimated to have raised the likelihood of working fewer hours than desired by the workers.     

Urban–rural income polarization and economic growth in China: evidence from the analysis of a dynamic panel data model

Using a dynamic panel data model and the system GMM, this article examines the relationship between urban–rural income polarization and economic growth at the provincial level in the period 1995 to 2010 in China. The estimated results and significant tests indicate that a certain degree of urban–rural income polarization is beneficial to economic growth at the provincial level in both stages for China as a whole, though the contribution of urban–rural income polarization to economic growth is relatively small. Aggravating urban–rural income polarization has a negative impact on economic growth in China. Based on a cluster analysis of regional economic growth at the provincial level, the authors carried out the same analysis separately for two categories of regions too. The results for those two categories of regions show that positive correlations also exist between urban–rural income polarization and economic growth in both stages, which are very similar to the analysis for the whole of China. In addition, a meaningful finding can be derived that the contribution of consumption growth rate to economic growth rate in the second stage is smaller than that in the first stage obviously.     

Is the natural resource production a blessing or curse for China's urbanization? Evidence from a space–time panel data model

This paper provides an analytical framework to evaluate under what conditions the natural resource production could promote or hinder urbanization process, focusing on factors mostly relevant for China. Considering both structure breaks and cross-sectional dependence as well as spatial spillovers, the study deploys a comprehensive approach to rigorously prove the validity of the proposed space–time panel data model that includes the second generation panel unit root test and panel cointegration, panel threshold regression and spatial panel Durbin model. The results not only offer strong evidences that the natural resource production non-linearly impacts on urbanization process, but also show that there exists a dynamic response over time and space as well as space–time diffusion impact, in which these percentages are different from each other confirming an asymmetric effect of the natural resource production on urbanization process.     

Is there a unit root in the inflation rate? New evidence from panel data models with multiple structural breaks

In this article, we examine whether or not the inflation rate for 17 OECD countries can be modelled as a stationary process. We find that (1) conventional univariate unit root tests without any structural breaks generally reveal that the inflation rate contains a unit root; (2) the KPSS univariate test with multiple structural breaks reveals that for 10 out of 17 countries inflation is stationary; and (3) the KPSS panel unit root test reveals strong evidence for stationarity of the inflation rate for panels consisting of countries which were declared nonstationary by univariate tests.     

Insider power and wage setting in transition: Evidence from a panel of large Polish firms, 1988–1994

We analyse wage setting behaviour in the period of transition using the `right to manage model'. The results show a significant change in wage bargaining in 1990. However, the insider power, measured by the employees' capacity to capture productivity gains, persists. The sensitivity of wages to productivity changes is much stronger on the upside than on the downside. In SOEs insiders capture important part of labour productivity gains. In firms transformed into Treasury owned joint stock companies insider effect is weaker. In privatised firms, the bargaining power of the employees is too weak to let them push up wages in response to labour productivity growth. These results are robust to the potential selection bias.     

Urban–rural income disparities and development in a panel data set of China for the period from 1978 to 2006

We examine the relationship between urban–rural income disparities and development in a panel data set of 30 provinces and regional subsets of China during the period of 1978 to 2006. There is an inverted-U relationship between the urban–rural income gap and per capita Gross Domestic Product (GDP). Financial development by scale widens the urban–rural income gap in all regional samples, while financial sector efficiency and rural bank loans may reduce it in some regions. Government spending raises the urban–rural income gap as well. We also examine the effects of urbanization, openness and education.     

The East-West German gap in revenue productivity:Just a tale of output prices?

East German manufacturers’ revenue productivity is substantially below West German levels, even three decades after German unification. Using firm-product-level data with product quantities and prices, we analyze the role of product specialization and show that the prominent “extended work bench hypothesis” cannot explain these sustained productivity differences. Eastern firms specialize in simpler product varieties generating less consumer value and being manufactured with less or cheaper inputs. Yet, such specialization cannot explain the productivity gap because Eastern firms are physically less productive for given product prices. Hence, there is a genuine price-adjusted physical productivity disadvantage of Eastern compared to Western firms.JEL: D24, L11, L2, O47     

Are the kinship networks a resource or a curse for small firms in post-communist countries? The case of Albania

Cross-sectional data are compiled from the 2002, 2005, 2008 and 2012 World Bank Living Standards Measurement Study databases for Albania. Based on responses from 1169 firms, the entrepreneurs’ kinship networks are found to influence firm activity in a positive and negative way. The positive contribution occurs through employment, be it formal or informal. The persisting impact of the kinship networks fades away, and business and friendship networks have gained importance in recent years.     

Citizens’ support for inter-municipal cooperation: evidence from a survey in the German state of Hesse

Inter-municipal cooperation (IMC) is often proposed as a politically feasible way by which rural municipalities can cope with intensified interregional competition and demographic change. We provide first evidence on citizens’ support for IMC using survey data from rural Germany. We find little evidence that citizens are more willing to support IMC in munici-palities that can – by the logic of economic theory – expect higher net benefits from IMC. Citizens’ support for IMC is primarily shaped by individual-level factors like the level of education, trust in local politicians and the degree of emotional attachment to the home mu-nicipality. Citizens’ beliefs regarding the economic and political consequences of IMC are found to have the largest marginal effect by far. Regressions predicting interpersonal differ-ences in these beliefs show that these beliefs have to be considered independent drivers of policy preferences. This result suggests that more research is needed to better understand the factors shaping citizens’ understanding of how economic policy works. This lack of under-standing applies to virtually all fields of economic policy.     

Saving,investment and capital mobility in EU member countries: a panel data analysis of the Feldstein–Horioka puzzle

ABSTRACT

In this paper, we reexamine the long-standing and puzzling correlation between national saving and investment in 14 European Union (EU) countries. We employ a panel data set for the period 1970–2015 and we apply recently developed maximum likelihood panel cointegration methodologies. We find that there exists a long-run relationship between savings and investment for this panel of EU member countries, with the savings retention coefficient being low in magnitude but statistically different than zero. Therefore, we argue that there is weak evidence in favour of the Feldstein–Horioka puzzle and that the long-run international solvency condition is maintained in most of these countries. This evidence implies a moderate degree of capital mobility which is consistent with the macroeconomic experience of these countries during the period under investigation.     

Cost effectiveness of asthma treatment with a breath-actuated inhaler: how has the story changed?

Abstract

Objectives: A database analysis evaluating the comparative costs and outcomes of asthma treatment with breath-actuated inhalers (BAIs) and metered-dose inhalers (MDIs) has previously been undertaken in 2001. This analysis found that, despite the higher acquisition cost associated with BAIs, economies elsewhere meant that the overall cost associated with BAIs was lower than MDIs. Between 2001 and 2007, the comparative price of MDIs was significantly reduced thus widening the gap between the comparative acquisition cost of MDIs and BAIs. Furthermore, the introduction of specific targets for asthma review included a requirement for regular checks on inhaler technique. Such initiatives may be expected to enhance the overall effectiveness of MDIs. Given the potential impact of such changes, it appeared to be timely to update the original database analysis to assess the extent to which the original findings have been altered by changes in the clinical and economic environment over the past 5 years.

Methods: As in all chronic diseases, it is important that economic analyses evaluate cost effectiveness over as long a period as possible, and so the 2006 analysis was conducted over a 12- and a 24-month time period.

Results: The results emphasised that the clinical benefits associated with BAIs for certain patients can still be translated into greater cost effectiveness, but that altered cost structures required a longer time period for the greater cost effectiveness of BAIs to become evident.

Conclusion: Since completing this study, the reimbursement costs for beclometasone MDIs have increased significantly (since October 2007) due to the discontinuation of Becotide and Becloforte. As a consequence of this higher acquisition cost for MDI inhalers, the current cost-effectiveness advantages of BAI compared to MDI can be expected to be even greater than that identified in the study.     

Testing for the stability of money demand in Italy: has the Euro influenced the monetary transmission mechanism?

Stability of money demand is a crucial issue for the efficacy of monetary policy. This is particularly true in the presence of significant exogenous shocks to the monetary system. By implementing the most recent econometric testing procedures, this article intends to investigate the consistency of the stability of money demand in Italy, one of the larger European Monetary Union (EMU) countries, before and after the EMU. Among others, the objective is, indeed, to ascertain the effect of a change in the currency regime on the monetary aggregates and to provide a valid empirical model which is a viable tool for policy performance.     

Competing specifications of the gravity equation: a three-way model,bilateral interaction effects,or a dynamic gravity model with time-varying country effects?

We investigate bilateral trade flows across the EU-15 countries from 1962 to 2003 by different specifications of the gravity model. We augment the basic gravity model with population and exchange rate variables, and then include time-varying country fixed effects, to account for Anderson and van Wincoop (Am Econ Rev 93(1):170–192, 2003) multilateral resistance terms. Then, following the previous theoretical derivations of the gravity model in the presence of panel data in a dynamic setting we change the specification of our gravity model. We compare the results of different specifications showing the improvement in each case. We claim the comparative superiority of the dynamic gravity model with time-varying exporter and importer fixed effects due to its higher explanatory power. Finally, we compare out-of-sample forecasting performance of different specifications of the gravity model.     

Populism and the return of the “Paranoid Style”: Some evidence and a simple model of demand for incompetence as insurance against elite betrayal

We present a simple model of populism as the rejection of “disloyal” leaders. We show that adding the assumption that people are worse off when they experience low income as a result of leader betrayal (than when it is the result of bad luck) to a simple voter choice model yields a preference for incompetent leaders even if all leaders have the same underlying probability of betrayal. These deliver worse material outcomes in general, but they reduce the feelings of betrayal during bad times. Some evidence consistent with our model is gathered from the Trump–Clinton 2016 election: on average, subjects primed with the importance of competence in policymaking decrease their support for Trump, the candidate who scores lower on competence in our survey (even amongst Trump supporters). But two groups respond to the treatment with a large (approximately 5 percentage points) increase in their support for Donald Trump: those living in rural areas and those that are low educated, white and living in urban and suburban areas.     

The impact of foreign direct investment on UK manufacturing: is there a profit squeeze in domestic firms?

This paper examines the extent to which foreign direct investment (FDI) in selected UK manufacturing sectors has an impact on reported profits in domestic firms. Foreign manufacturing firms are characterized by relatively high labour productivity and low wage shares. Entry by foreign firms not only impacts on domestic market shares, but also on domestic cost conditions. As a result, profitability in the indigenous sector may be reduced. There are a number of policy implications of this analysis which are explored.     

Healthcare costs for Crohn’s disease patients treated with infliximab: a propensity weighted comparison of the effects of treatment adherence

Objective:

The objective for the research was to evaluate the direct healthcare costs for Crohn’s disease (CD) patients categorized by adherence status.

Methods:

Adult patients with ≥1 claim for infliximab and ≥2 claims for CD who were continuously insured for 12 months before and after their first infliximab infusion (index date) were identified in a 2006–2009 US managed care database. Patients were excluded if they had rheumatoid arthritis claims, received infliximab billed as a pharmacy benefit, or received another biologic drug. Patients were categorized as being either adherent or intermittently adherent to infliximab using a pre-defined algorithm. Total and component direct costs, CD-related costs, rates of surgery, and days of hospitalization were estimated for the 360-day post-index period. Propensity weighted generalized linear models were used to adjust the cost estimates for potential confounding variables.

Results:

The total propensity weighted cost for infliximab adherent patients was $40,425 (95% CI?=?[$38,686, $42,242]), compared to $41,082 (95% CI?=?[$38,163, $44,223]) for the intermittently adherent (p?=?0.71). However, adherent patients had lower total direct medical costs, exclusive of infliximab, that were $13,097 (95% CI?=?[$12,141, $14,127]) compared with $20,068 (95% CI?=?[$17,676, $22,784]) for intermittently adherent patients as a result of substantially lower hospital and outpatient costs (p?Conclusions:

Greater drug-related costs for infliximab adherent patients were offset by lower costs from hospitalization and outpatient visits. These findings indicate that adherent patients have improved clinical outcomes, at a similar aggregate cost, than patients who are only intermittently adherent to therapy.     

Hollander, de Vivo and the 'further evidence' for the corn model interpretation of Ricardo: a conspiracy of silence?

This paper reconsiders the debate between de Vivo and Hollanderover the ‘further evidence’ in favour of Sraffa's‘corn model’ interpretation of Ricardo in the lightof Torrens's Letter to Lord Liverpool (1816). It is argued thatthe Letter provides unique evidence of the influence on Torrensof Ricardo's Essay on Profits (1815); and that, contrary tode Vivo, the evidence is not that of a ‘corn model’influence. It is further argued that the manner in which theLetter has been dealt with is unsatisfactory. The shortcomingsin Hollander's position are traced to peculiarities in his long-standinginterpretation of the early Ricardo.
