Latvijas Banka maintains and develops economic modelling tools in order to ensure high-quality and independent analytical vision of monetary and economic policy making.

Economic models are based on economic theory, and they are calibrated to the structure of Latvia’s economy.

Models of Latvijas Banka are used on a regular basis to make macroeconomic projections, analyse current economic developments and evaluate economic policy proposals.  

STIP model

The short-term inflation projections (STIP) model is used by Latvijas Banka to forecast future inflation in Latvia and assess developments in various inflation components.

The STIP model exploits statistical correlations between the harmonised index of consumer prices and its major determinants, i.e. wages, global food prices and oil prices. The STIP model is an important tool used by Latvijas Banka in the forecasting process.

Computable general equilibrium (CGE) model with the fiscal sector

The computable general equilibrium (CGE) model contains detailed information on sectors and goods, taking account of the input-output relationships between various sectors of the economy.

Latvijas Banka uses the CGE model for analysing the direct and indirect effects of various macroeconomic developments and fiscal policy changes on the overall economy and selected sectors on a regular basis.

The current version of the model comprises 63 sectors and 63 goods using data from input-output as well as supply and demand tables for 2015. The number of equations in this model is close to 30 thousand.

While developing Latvia's CGE model, special attention was paid to the fiscal block: the model consists of the major government expenditure types and five revenue sources, including four major taxes such as the personal income tax, mandatory social security contributions, value added tax and excise tax.

Latvijas Banka has merged the EUROMOD and CGE models into a single CGE-EUROMOD model, which is used to analyse the impact of macroeconomic changes on income of various social groups as well as to assess the indirect effect of changes in taxes and benefits.

EUROMOD is a European tax-benefit microsimulation model. It enables analysis of the changes in tax and benefit rules and calculates the effect of these changes on disposable income of different social groups. Thus, EUROMOD is an appropriate tool to assess the effect of changes in taxes and benefits on income inequality and poverty rates.

The model has been developed and maintained by the Institute for Social and Economic Research at the University of Essex in cooperation with national expert teams. The Latvian national expert team is based at the Baltic International Centre for Economic Policy Studies (BICEPS). EUROMOD is a static model based on the data obtained from the survey on income and living conditions (EU-SILC). 

Latvijas Banka has merged the EUROMOD and CGE models into a single CGE-EUROMOD model, which is used to analyse the impact of macroeconomic changes on income of various social groups as well as to assess the indirect effect of changes in taxes and benefits.

Short-term models used to forecast Latvia's gross domestic product (GDP)

Latvijas Banka employs the following models to forecast GDP growth

  • The barometer compiles information on approximately 60 monthly economic indicators having the highest correlation with the target (GDP) time series. The barometer utilised for tracking Latvia's economic activity adopts a similar framework, as developed for the KOF Swiss Economic Barometer in Abberger et al. (2014, 2017).
  • The dynamic factor model (DFM) is based on the Kalman filter. The DFM allows for simultaneous modelling of economic time series observed at different frequencies (quarterly and monthly). The model built for the use with Latvian data adopts the framework of the EuroSTING indicator of Camacho and Perez-Quiros (2010). Siliverstovs (2012, 2016) applies the same framework for modelling of the Swiss economy.
  • The suite of nowcasting models consists of several short-term econometric (bridge, factor and VAR) models. It is used to nowcast short-term economic activity.
  • LATIN economic activity indicator is obtained via the regularised multivariate direct  filter using 220 economic time series of the Latvian economy, and to a lesser extent, of the Lithuanian, Estonian and euro area economy.

DSGE model for Latvia

The DSGE model for Latvia is a dynamic, stochastic general equilibrium model for Latvia as a small open economy in the euro area. It belongs to the class of New-Keynesian models.

DSGE models are used by monetary, fiscal and macroprudential institutions to analyse policy scenarios, explain historical developments and carry out forecasting.

DSGE models are based on general equilibrium theory and microeconomic principles. Unlike real business cycle models, New-Keynesian models include various (inter alia, price) frictions and market failures. Meanwhile, in contrast to CGE (computable general equilibrium) models, DSGE models are dynamic, and expectations of market participants play an important role in their results. In the wake of the global financial crisis, DSGE models were supplemented with financial market frictions. Currently, DSGE models represent the predominant type of structural models used in the theoretical economics literature and economic policy institutions.
