BackgroundThe objective of this study is to estimate the sensitivity of cigarette quantity demanded to price and income changes in Montenegro.Data and methodsThe sensitivity of cigarette quantity demanded to price and income changes was estimated using micro and macro analysis. Micro analysis implied the use of Deaton’s model on Household Budget Survey data (2006–2017). In macro analysis, conventional static demand model is applied using error correction and autoregressive distributed lag time series methodology on annual time series aggregated data (2001–2017).ResultsThe same results were obtained using micro and macro analysis which contributes to the objectivity of the conducted research. Results derived from the Deaton’s model indicate a negative price elasticity of cigarettes in the range between −0.62 and −0.80 (conditional and unconditional), while in macro model estimated price elasticity is in that range and equals −0.68. Simulation results confirm the efficiency of excise tax policy changes, having an evident decrease in consumption and increase of public revenues.ConclusionAnalysis of the tobacco market and regulatory environment suggests that the increase of excise and other taxes on tobacco have an important direct impact on the reduction of cigarettes and other tobacco products consumption. Our estimates of long and short-run price elasticity show that direct impact is strong and very much in accordance with the results obtained so far for other low-income and middle-income countries. This paper gives a contribution to the analysis of price elasticity of demand for cigarettes, which was for the first time conducted in Montenegro.
This paper examines corporate leverage and its determinants on panel of 921 large Western European companies from 2003 to 2010. The results proved a substantial influence of estimated variables on changes in target debt or leverage ratio. Apart of the determinants from the «core" model, I test the influence of stock price variations on changes in capital structure to conclude if companies «time" the market. The estimation procedure of target debt ratio was performed using Fixed-Effect and FGLS methods. The results were compared to the results of often used methodology in previous research-OLS and Tobit regression. I found statistically significant and negative correlation between target leverage ratio and tangibility, market to book, profitability, product uniqueness and total return (average stock return) and statistically significant and positive correlation between target leverage ratio and size. The results suggest the mix of trade-off and pecking order theory predictions and are consistent with findings of previous studies. Future research should focus on impact of leverage deficit (deviations from target leverage ratio) on corporate decisions in Europe.
In this paper we examined adaptive markets hypothesis (AMH) using three factors we assumed that affect weak-form of market efficiency: observation period, time horizon represented by rolling window sizes and data aggregation level. We have analyzed market value weighted index MONEX20, which is proxy from Montenegro equity market, over 2004-2011 period. Rolling window analysis with fixed parameter in each window is employed to measure the persistence of deviations from a random walk hypothesis (RWH) over time. Actually, using rolling sample approach we checked whether short-range linear dependence is varying over time. This method was applied on the first order serial autocorrelation coefficients (AC1), as well as on runs test, since evidence on non-normality properties of MONEX20 suggests using non-parametric test. The evidence was found that all three factors impact degree of weakform Montenegro equity market efficiency which has serious consequences on profit opportunities over time on this market.

The objective of this study was to estimate the sensitivity of spirit quantity demanded for price and income changes in Montenegro and to show the effectiveness of taxation-policy changes in the reduction of spirit consumption. It is the first study on this topic in Montenegro, where adverse effects of alcohol are recognized as an important obstacle in achieving Sustainable Development Goals (SDGs). The price elasticity of spirits was estimated using Deaton’s methodology on the Household Budget Survey (HBS) data in the period of 2006–2017. Cigarettes were included as a control variable as, along with spirits, they are one of the most harmful substances used in Montenegro. Using these results, we simulated the effects of spirit use on public revenue. The results show that the spirits’ own price elasticity equaled −0.45, while the cross-price elasticity equaled −0.17, showing that spirits and cigarettes are complementary goods. These results, along with elasticities calculated by sex (male, −0.55; female, −0.5), income groups (low income, −1.16; middle-income, −0.46; high-income, −0.26), and for the working-age group (−0.74), demonstrate that an increase in excise taxes could be a very efficient tool in decreasing the adverse effect of spirits and cigarettes on household member’s productivity, health, and budget, which is in line with SDGs. An efficient road map for sustainable development for Montenegro must include the reduction of health-harmful substance use through excise tax increase.
BackgroundThe main goal of this study was to examine the responsiveness of smoking prevalence and cigarette consumption to price and income changes by income groups and the effectiveness of tax policy changes to reduce cigarette consumption in Montenegro.Data and methodsA two-part model was applied to estimate smoking participation, smoking intensity price and income elasticity. The first part of the model applies logit regression, while the second uses Deaton’s model to improve the validity and objectivity of conditional (smoking intensity) elasticity results. A generalised linear model (GLM) was applied to verify robustness. The reason for this is that Deaton’s model is commonly used in the analysis of Household Budget Survey (HBS) data, especially when households do not report the market price. Moreover, using this model, it is possible to capture the shading of quality to price change. The analysis used HBS data (2006–2017).ResultsThe estimates indicate that tobacco pricing policies had a much higher impact on smoking prevalence in the low-income group (price elasticity of −0.595) relative to the high-income group (price elasticity of −0.344). The same conclusion could be drawn for the smoking intensity elasticity: the high-income group was the least affected by changes in price (price elasticity of −0.258). At the same time, the most affected was the low-income group, with price elasticity of −0.424. Poorer households spent a larger share of their budget on cigarettes. The simulation results confirm that increases in the specific excise taxes of 58.3% on tobacco would reduce total cigarette consumption by 11.25% while increasing the collection of government revenue by 8.07%.ConclusionSmoking prevalence and consumption are very responsive to price and income changes, with considerable differences in elasticities between income groups. The taxation policy has a positive impact on changing patterns of consumption and public revenues across each income group. Low-income and middle-income households would benefit the most, while on the other hand, the highest revenue collection was generated from the wealthiest group. Our results align with results obtained so far for other low-income and middle-income countries. This paper contributes to the analysis of the smoking prevalence and cigarette consumption responsiveness to price and income changes, which was conducted for the first time in Montenegro.
