Working Paper Series

working paper series.jpg

Working papers disseminate economic research relevant not only to the tasks and functions of the Bank of Lithuania and of the European System of Central Banks but also appealing more broadly to the academic community in economics and finance. They present, discuss and analyse the results of original and academically rigorous theoretical and/or empirical research. Working papers constitute the basis for publications in leading academic journals, making contributions to the existing literature in the fields of economics and finance. They encourage collaboration between the researchers of the Bank of Lithuania and other central banks, Lithuanian and foreign universities and research institutes.

Papers are only available in English.

The Effect of the Euro Changeover on Prices: Evidence from Lithuania

  • Abstract

    At the aggregate level, I find that the euro changeover did not lead to a significant change in the overall inflation rate between 2015 and 2019 in Lithuania. When the measures are diversified, however, some inflationary effects emerge in sub-categories. I therefore analyze this heterogeneity at the disaggregated level using a large sample of prices that constitutes the CPI from 2010 to 2018. I show that significant price changes have been confined to the low-weighted components of the HICP. This explains why a spike in the overall price level did not occur at the time of the changeover.

    Keywords: Euro changeover, synthetic difference-in-differences, regression discontinuity in time, price changes.

Firm Heterogeneity, Variable Markups, and Multinational Production: A Review from Trade Policy Perspective

  • Abstract

    This paper surveys the main ingredients and results of heterogeneous firms trade policy literature that has been developing since the early 2000s. First, I present the stylized facts regarding firm heterogeneity, firmlevel markups, and multinational production’s global structure. I then survey the trade policy papers that build on the workhorse model of firm heterogeneity. Third, I summarize the recent development of theoretical approaches of modeling the firm-level markups and its trade policy implication. Fourth, I discuss the theoretical frameworks that incorporate multinational production into heterogeneous firms’ framework and their trade policy implication. Finally, I discuss directions for future research and offer suggestions for further readings.

    Keywords: Trade policy, Firm heterogeneity, Variable markups, Multinational production.

The Factor Analytical Approach in Trending Near Unit Root Panels

  • Abstract

    In this study, we re-visit the factor analytical (FA) approach for (near unit root) dynamic panel data models, whose asymptotic distribution has been shown to be normal and well centered at zero without the need for valid instruments or correction for bias. It is therefore very appealing. The question is: Does the appeal of FA, which so far has only been documented for fixed effects panels, extends to panels with incidental trends? This is an important question, because many persistent variables are trending. The answer turns out to be negative. In particular, while consistent, the asymptotic normality of FA breaks down when there is an exact unit root present, which limits its applicability.

Two-Stage Instrumental Variable Estimation of Linear Panel Data Models with Interactive Effects

  • Abstract

    This paper analyses the instrumental variables (IV) approach put forward by Norkutė et al. (2021), in the context of static linear panel data models with interactive effects present in the error term and the regressors. Instruments are obtained from transformed regressors, thereby it is not necessary to search for external instruments. We consider a two-stage IV (2SIV) and a mean-group IV (MGIV) estimator for homogeneous and heterogeneous slope models, respectively. The asymptotic analysis reveals that: (i) the √NT-consistent 2SIV estimator is free from asymptotic bias that may arise due to the estimation error of the interactive effects, whilst (ii) existing estimators can suffer from asymptotic bias; (iii) the proposed 2SIV estimator is asymptotically as efficient as existing estimators that eliminate interactive effects jointly in the regressors and the error, whilst; (iv) the relative efficiency of the estimators that eliminate interactive effects only in the error term is indeterminate. A Monte Carlo study confirms good approximation quality of our asymptotic results.

    Keywords: Large panel data, interactive effects, common factors, principal components analysis, instrumental variables.
