We examine the effect of borrowing constraint facing new immigrants on the process of their assimilation in the new society. We shall do so in a two-period model. In period 1, immigrants invest, with some costs to them, in trying to assimilate. The probability of success in this endeavor depends on the amount invested and also on the level of the provision of a “public” good paid for by lump-sum taxation of “natives”. Those who succeed enjoy a higher level of productivity and therefore wages in period 2. The level of investment is endogenously determined. Assimilation also affects remittances by immigrants. Given this framework, we examine the effect of public support on the degree of assimilation and income repatriation. We do so under two scenarios regarding the credit market facing new immigrants. In the first, they can borrow as much as they want in period 1 at an exogenously given interest rate. In the second scenarios, there is a binding borrowing constraint. We compare the equilibrium under the two scenarios.

Gaussian copula is by far the most popular copula used in the financial industry in default dependency modeling. However, it has a major drawback – it does not exhibit tail dependence, a very important property for copula. The essence of tail dependence is the interdependence when extreme events occur, say, defaults of corporate bonds. In this paper, we show that some tail dependence can be restored by introducing stochastic volatility on a Gaussian copula. Using perturbation methods we then derive an approximate copula – called perturbed Gaussian copula in this paper.

A univariate GARCH(p,q) process is quickly transformed to a univariate autoregressive moving-average process in squares of an underlying variable. For positive integer m, eigenvalue restrictions have been proposed as necessary and sufficient restrictions for existence of a unique mth moment of the output of a univariate GARCH process or, equivalently, the 2mth moment of the underlying variable. However, proofs in the literature that an eigenvalue restriction is necessary and sufficient for existence of unique 4th or higher even moments of the underlying variable, are either incorrect, incomplete, or unnecessarily long. Thus, the paper contains a short and general proof that an eigenvalue restriction is necessary and sufficient for existence of a unique 4th moment of the underlying variable of a univariate GARCH process. The paper also derives an expression for computing the 4th moment in terms of the GARCH parameters, which immediately implies a necessary and sufficient inequality restriction for existence of the 4th moment. Because the inequality restriction is easily computed in a finite number of basic arithmetic operations on the GARCH parameters and does not require computing eigenvalues, it provides an easy means for computing “by hand” the 4th moment and for checking its existence for low-dimensional GARCH processes. Finally, the paper illustrates the computations with some GARCH(1,1) processes reported in the literature.

This chapter examines the implications of introducing “robot capital goods” in a one-sector optimal growth model, assuming a high elasticity of substitution between workers and robots. The growth path will either converge to a steady state, or involve endogenous growth without scale effects. In the latter case, the optimal growth rate of output per worker will converge to a positive number that depends on both technological and preference parameter. Moreover, the rate of growth could be increased permanently by subsidizing saving.

Purpose: This research study addresses the key issues of the fiscal policies and tax system in Kosovo to align with the contemporary tax principles and requirements of the European Standards.

Design/methodology/approach: In order to explain the fiscal policies and tax system in Kosovo, the authors provide an overview of the fiscal policies and tax system in the country. The authors focused on the building and development of the tax system, the role of the tax policy in economic development and the macro-fiscal stability. The methodology approach is based on primary and other secondary sources, such as academic literature, the reports provided by the Ministry of Finance and international institutions, tax law and other available important statistical data.

Findings: The chapter substantiates and confirms the need for tax reforms in order to have an adequate tax system oriented to indirect tax, changing the structure of tax collection for border tax into domestic tax, simplification of the legal procedures, improvement of management and audit systems, reducing the informal gray economy and to have a gradual growth-friendly fiscal policy. Positive fiscal performance continued, although there is still room to improve the execution of revenues.

Practical Implications: This chapter highlights the fact that Kosovo needs to intensify their fiscal reforms to build a sustainable tax system in order to meet the criteria of the EU tax system and policies.

Originality/value: The authors define the needs for strengthening the budget revenues, taking strong and coordinated steps to improve the management and collection of the revenues from indirect and direct taxes. Moreover, the authors show that the Kosovo tax system is broadly in line with the EU acquis and needs reform in order to have a sustainable tax regime.

Purpose: This chapter aims to address the problem and explore the process of creating the new ‘markets of tomorrow’ from the perspective of the technological inequalities arising in this context and leading to conflicts in international trade, thus prompting the creation of promising areas of conflict management.

Design/methodology/approach: The study is carried out using the comparative analysis methods through the review of analytical data, as well as using the qualitative structural and logical analysis method.

Findings: This chapter reviews the factors that determine the benefits and limits of participating in the creation of the new ‘markets of tomorrow’ in some of the world’s countries. Prospects and recommendations are identified to prevent or partially mitigate the technological inequalities constituting a barrier to the creation of new ‘markets of tomorrow’, provoking conflict in international trade and promoting the development of promising areas of conflict management.

Originality/value: The results of the study generally supported the assumption that recovery from the economic downturn associated with the COVID-19 pandemic requires a comprehensive and sustained economic transformation capable of delivering economic growth that would contribute to the broader social and environmental goals to be achieved over the coming decade. Implementing such a transformation will require the active creation of ‘markets of tomorrow’ through a creative combination of disruptive technological and socio-institutional innovations. The aim is not only to produce more or in a better way but also to transform economies by creating new technological and institutional systems that can address some of today’s most pressing social problems, in particular to mitigate technological inequalities and prevent conflicts from developing.

The relevance of the research topic is due to the high importance of the Belt and Road Initiative (BRI) for increasing the presence of China in the markets of the countries of the New Silk Road. The topic becomes more relevant due to the ambiguous results of the BRI, although it was launched in 2013. On the one hand, the effect for China is growing. On the other hand, the effect for the participating countries has not yet reached the level initially declared.

The chapter aims to identify the main challenges and advantages of the BRI based on the involvement of countries and their markets in the trade and economic system formed by China.

The research novelty lies in studying the economic goals and objectives of the People's Republic of China (PRC) under the BRI and the possibilities of using the trade and economic system created by the PRC for developing the PRC and the BRI member countries.

The authors found that the initiative is designed to better integrate the economy of China at the regional and global level, promote the socio-economic progress of the less developed western territories of the country and stabilize foreign trade and domestic socio-economic processes in conditions of global instability. The authors justify that this initiative, uniting more than 80 countries in Asia, Africa and Oceania, will strengthen China's role in the world economy and trade, form a specific international trade and economic platform under the leadership of China and provide the country a leading position in at least three parts of the world.

The authors use traditional economic research methods, such as scientific abstraction, deduction, analysis and synthesis. Additionally, the authors use the method of visualization based on the application of the statistical method.

This chapter is aimed at proving that digital competition is widespread, and the unequal distribution of technologies in entrepreneurship leads to business conflicts. Official Russian and international statistical data for 2021 is used. The variation analysis method is used to reveal differences in the level of digital development of enterprises from various sectors of the Russian economy, as well as differences in the level of digital development of enterprises throughout the world. The contribution of this chapter to the literature consists of the development of the Conflict Theory through the identification of business conflicts in digital competition as a particular type of business conflict, which is characterized by an unequal distribution of technologies in entrepreneurship. The novel nature of the chapter lies in the fact that it has for the first time systematized the factors of unequal distribution of technologies in entrepreneurship. The authors’ classification of business conflicts in digital competition in entrepreneurship according to their determining factors has been put forward. The essence has been clarified and the cause-and-effect relations of business conflicts in digital competition in entrepreneurship have been identified. Recommendations have been developed for the management of business conflicts in digital competition in entrepreneurship, taking into account their peculiarities.
