Mathematical Model of MMT with Profit Return under Monopolistic Competition

Even under constant returns to scale technology there is a positive profit return if the goods are produced in monopolistic competition. By a two-periods overlapping generations (OLG) model with production in monopolistic competition under constant returns to scale in which the economy grows by technological progress and the older generation consumers receive the profits, we consider the problem of budget deficit. We show that the budget deficit equals the difference between the net savings of the younger generation consumers excluding the profits received in the future and that of the older generation consumers in each of the following cases. Also, the following results will be proved. 1) A budget deficit is necessary to realize full employment with constant price when the economy grows. 2) If the budget deficit exceeds the level necessary and sufficient to maintain full employment in a growing economy with constant price, inflation will occur. A stable budget deficit is necessary to prevent further inflation. 3) If the budget deficit is insufficient to maintain full employment, a recession with involuntary unemployment occurs. We can overcome a recession and restore full employment making a budget deficit larger than the one necessary and sufficient to maintain full employment without a recession. Since we can maintain full employment by constant budget deficits, we should not offset the deficit created for overcoming the recession by budget surpluses.

Modern Problems and Prospects for the Development of the Insurance Market in the Russian Federation

The role of insurance in a person’s life is undoubtedly great because it serves as the most effective tool in case of loss of property, health problems, business protection, etc. The purpose of the article is to assess the current state of the insurance market in Russia and identify problems that arise during its functioning. The research methodology consists in summarizing and comparing data characterizing various components of the insurance market. The article analyzes the current state of the insurance market in Russia with a falling number of insurers by more than 20 % over the past 3 years, the share of top insurers continues to grow every year, over the past 3 years the growth has amounted to 12 %. Calculations that indicate a change in the level of concentration in the insurance market of the Russian Federation have been made. Based on the results of the analysis, it was concluded that there is monopolistic competition in the market. The main factors influencing the level of competition in the market under consideration, namely, barriers to entry into the industry and their impact, were studied Due to the relevance of the research, the analysis of the impact the pandemic has on the Russian insurance market was carried out and the prospects for the development of the market were considered. Identifying the weaknesses of insurers made it possible to determine the priority areas for further development: intensive digital transformation of business, marketing, advertising.

Fiscal Policy as a Solution to Involuntary Unemployment

We show the existence of involuntary unemployment based on consumers’ utility maximization and firms’ profit maximization behavior under monopolistic competition with increasing, decreasing or constant returns to scale technology using a three-periods overlapping generations (OLG) model with a childhood period as well as younger and older periods, and pay-as-you-go pension for the older generation, and we analyze the effects of fiscal policy financed by tax and budget deficit (or seigniorage) to achieve full-employment under a situation with involuntary unemployment. Under constant prices we show the following results. 1) If the realization of full employment will increase consumers’ disposable income, in order to achieve full-employment from a state with involuntary unemployment, we need budget deficit (Proposition 1). 2) If the full-employment state has been achieved, we need balanced budget to maintain full-employment (Proposition 2). We also consider fiscal policy under inflation or deflation. Additionally, we present a game-theoretic interpretation of involuntary unemployment and full-employment. We also argue that if full employment should be achieved in equilibrium, the instability of equilibrium can be considered to be the cause of involuntary unemployment.

Analysis of the insurance market in the Russian Federation and trends in its transformation

Objective: To characterize the evolution of the insurance market in the Russian Federation and analyze its current state. To determine the evolution features and trends of the insurance market in Russia and provide its advanced model. To identify opportunities and threats, as well as the cur-rent problems of the evolution of the Russian insurance market. Methods: Comparison of the char-acteristics of the state and evolution of insurance markets around the world. Analysis of statistical data from official sources of the Bank of Russia and changes in the insurance market measures. As-sessment of market concentration using traditional methods of industry markets analysis. Results: It has been established that in economically developed countries the insurance market is character-ized by monopolistic competition. The specific forms of competition in the insurance market have been classified. The evolution features and trends of the Russian insurance market have been re-vealed. In view of the existing evolution trends, an advanced model of the Russian insurance mar-ket has been determined, and the opportunities and threats for the future market condition have been characte¬rized. Practical importance: The study findings may be of interest to state structures regulating the insurance market of the Russian Federation, since the increased attention of regula-tors to the Russian insurance market in connection with the threat of its monopolization requires preventive measures as regards the antimonopoly policy and close monitoring of the insurance market changing state. A more detailed analysis of individual territorial and product segments of the Russian insu¬rance market well have to be conducted.

Retrospective analysis of foreign investment in the context of the evolution of economic theories

The article provides a retrospective analysis of the formation and evolution of foreign direct investment in terms of various economic theories taking into account changes in the stages of socio-economic development. The study of these historical and economic issues was carried out using systematic analysis and historical method; which allowed us to identify the genesis and analyze the evolution of economic theories on the formation and development of foreign direct investment. The author conducted a detailed study of the history of investment activities and management of foreign direct investment from the oldest origins in the ancient world to modern forms of innovation. It was found that at different times, repre- sentatives of various economic theories (open economy, market modernization, monopolistic competition, international capital movements, etc.) worked on under- standing complex investment processes, risk management and methods of obtaining economic benefits, who considered foreign direct investment as a guaranteed im- provement and development of society. The analysis of scientific literature and statistics shows positive social, po- litical, economic, technological and other effects of investment activities: job creation and training, export diversification and improvement of export perfor- mance, introduction of science-intensive technologies, activation of local firms – suppliers and subcontractors, the introduction of effective management methods, foreign exchange inflows, etc. Analyzing the genesis of economic theories, opinions and research, we conclude that humanity, feeling the need for savings, pays considerable attention to investment. The stages of the investment economy and the choice of methods of control over them indicate the urgency of this problem, and today scientists continue to discover new aspects of investment opportunities and develop innovative forms, mechanisms, tools of investment policy. Key words: economic theories, foreign direct investment, investment activity, international capital movement.

Is Industry Size a Carrier for Wage Inequality? A Panel Study Addressing Independent Variables of Inherently Different Sizes across Units

We address how independent variables of inherently different sizes across units, e.g., small vs. large industries, in panel regression is an advantage interpretively. Analyzing a Norwegian industry panel, we find that wage inequality is a function of industry size, particularly size increase, in an absolute number of firms. A possible reason is that specialized skilled employees negotiate higher wages when there are many legal entities. The findings can also imply that wage inequality is more sensitive to random change, particularly an increase, in large rather than small industries. We conclude that particularly large industries are positive carriers of wage inequality and discuss potential underlying causal mechanisms such as monopolistic competition.
