Trade Liberalization and Welfare Inequality: A Demand-Based Approach
The Scandinavian Journal of Economics. 2012. Vol. 114. No. 4. P. 1296–1317.

There is strong evidence suggesting that different income groups consume different bundles of goods. Hence, trade liberalization can affect welfare inequality via changes in the relative prices of goods consumed by different income groups (the price effect). In this paper, I develop a framework that enables us to explore the role of the price effect in determining welfare inequality. I find that trade liberalization does benefit some income classes more than others. In particular, I show that the relative welfare of the rich with respect to that of the poor has a hump shape as a function of trade costs.

This paper proposes Covariate-Balanced Weighted Stacked Difference-in-Differences (CBWSDID), a design-based extension of weighted stacked DID for settings in which untreated trends may be conditionally rather than unconditionally parallel. The estimator separates within-subexperiment design adjustment from across-subexperiment aggregation: matching or weighting improves treated-control comparability within each stacked subexperiment, while the corrective stacked weights of Wing et ...

This article is devoted to the phenomenon of intrinsic motivation, to understand which two models are proposed. We study how positive/negative intrinsic motivation to work (experienced utility) affects worker's individual labour supply (model I) and the amount of effort they exert (model II). In model I, we use intrinsic motivation to explain the positive/negative slope ...

In this paper, we develop a formal mathematical model aimed to explain the Dunning-Kruger effect that beginners systematically overestimate their own competence in various fields of knowledge and activity. We argue that the Dunning-Kruger effect arises from the emotional nature of confidence combined with unknown unknowns that it simply can not take into account due ...

This paper attempts to model the evolutionary theory of modernization and democratization. The model reflects the key provisions of R. Inglehart and C. Welzel's theory and provides a microfoundation for the adaptation of subjective values to the objective importances of the survival factors and the structure of the labour markets from the perspective of evolutionary ...

Many competitive environments allow for a third party to be indirectly involved by supporting one or both sides in the conflict. Such support can come from trade partners, colleagues, or allies, who can in turn benefit from a supported party's success. We use theory and an experiment to investigate how support relationships develop endogenously in ...

The study explores a psychological phenomenon of inaction inertia-avoiding action after missing a more favourable opportunity. Unlike action inertia (e.g.,sunk costs effect), inaction inertia has been less studied, particularly in economic contexts. Considering the reference dependent nature of the phenomenon, I build on the work of Kőszegi and Rabin (2006) to examine how past experiences ...

Simplified tax regimes with explicit eligibility thresholds are a common tool which reduces tax burden but distorts firms’ behavior, creating local bunching just below the threshold. However, we show that when firms have access to business splitting their responses extend far beyond the local margin. Our model demonstrates that splitting reduces local bunching but amplifies ...

In recent years, an emerging body of empirical research has shown that tax audits, in addition to recovering unpaid taxes (direct effect), increase future tax compliance (indirect or dynamic effect). This literature also suggests that updating expectations induced by audit experience plays an important role in explaining this indirect effect. However, exactly how taxpayers form ...

While the emerging empirical literature shows that collateral tax sanctions (CTSs) - such as driver’s license suspensions or passport denials - appear to be effective instruments to enforce tax debt collection, there are still few theoretical arguments to explain why. In this paper, I model enforcement of tax debt collection and provide a new rationale for why it could ...

We study the application of factor investing in the market for real estate (REITs). The analysis of traditional factor strategies, such as momentum, value, size and profitability, reveals their unstable and atypical behavior in comparison to the equity market, however, there is a strong momentum effect in the factor strategies. We propose a new dynamic ...

В данной статье рассматривается реакция российских предприятий обрабатывающей промышленности на ужесточение экономических санкций с акцентом на период после 2022 года. Хотя санкции в целом негативно сказываются на экономическом росте и эффективности деятельности компаний, есть некоторые свидетельства того, что они также могут подталкивать компании к инновациям, а негативный эффект преодолевается при помощи адаптации компании. Исследование заполняет ...

Innovation has long been at the center of debates in economics, management, and organizational studies. However, innovation is never free of uncertainty and risk. Every act of innovation implies a departure from established paths and a willingness to embrace the unknown. From the beginning it's never clear if there is an audience which appreciates the ...

strongly predicts positive changes in income poverty and inequality. Our approach was

This paper develops a modeling technique of “attainable profit” functions, applying it to two models of monopolistic competition. First, it revisits the Krugman's classical trade model in the most general form: several asymmetric countries and non-specified additive utility functions. We establish the weakest conditions on utilities, sufficient for the existence of equilibria. These conditions are ...

We study the canonical Krugman (1979) trade model with non-CES preferences that yield autarky at finite trade costs. We prove a non-monotone impact of gradual trade liberalization. At first, near autarky, emerging trade reduces world welfare, while at free trade it becomes large enough to be beneficial (Krugman's result). This non-monotonicity persists under heterogenous firms. ...

Our novel approach enriches the general additive monopolistic competition model with a space of product characteristics: consumers’ “ideal varieties”. This paper bridges two traditions in modelling markets with horizontal product differentiation: the Hotelling’s (Econ J 39(153):41–57, 1929) “address economy” and Chamberlinian Dixit–Stiglitz monopolistic competition. Unlike Hotelling, our partially localised competition involves intersecting zones of service among producers. ...

In order to study the structure of society, sociologists usually distinguish several homogeneous social groups, or classes. The most common division consists of three groups: upper, middle and lower classes. Such a partition is traditionally based on a subjective (exogenous) criteria adopted by a particular researcher.
