Closing pcy Differences Between Old and New Members • Growth accounting literature (Solow (1957), Prescott (1998) and Hall and Jones (1999), etc.) stresses: • Changes in total factor productivity (TFP) account for the largest part of economic growth. • International differences in TFP account for the bulk of international differences in pcy.

Income/Productivity Convergence is Accompanied by Structural Change • Kuznets (1966) – pervasive pattern of structural change accompanying economic development. • Over-industrialization, over-“agrarianism” and neglect of service sector under Communism (Gregory, 1970; Ofer, 1976) due to ideology and “common sense”.

Why worry? • Can TFP growth continue? • What are the effects of structural change on TFP growth? TFP in New EU Members
Barriers to Continued TFP Growth in New Members • Reforms cease – better institutions yield higher TFP. • Outward opening slows – globalization and FDI inflows raise TFP. • Granick - Prescott effects wear off. • EE has a poor record of TFP growth. TFP in New EU Members
EE’s record of TFP • Slowdown in Soviet TFP growth noted in 1960s (Kaplan, 1968). • We were confused by Weitzman (1970) and Easterly and Fischer (1995). • Studies of EE economies used variety of models & statistical techniques but all came to the same conclusion. By the early 1980s, only source of growth was “extensive” – TFP was zero. • If determinants of the level of TFP are slow to change, current TFP growth may be temporary TFP in New EU Members
Structural Change • Is the structural change we have seen in EE a source of positive change in TFP? • Development literature (e.g.,Herrendorf and Valentinyi (2006); Hsieh and Klenow (2007); Bah(2008)) suggest that TFP levels differ among sectors. TFP in New EU Members
Why Not Apply Growth Accounting to Transition Economies ? • Sectoral Data Not Available. • Even Aggregate Capital Stocks Suffer from Major Defects (Campos and Coricelli (2002)). • Large but unmeasured depreciation and abandonment • Moral depreciation – large changes in pattern of production and in technology • Estimates of TFP depend critically on “revisions” of “official” data (Izumov and Vahaly (2006, 2008)) TFP in New EU Members
This Paper • Builds a dynamic 3 sector (Agriculture, Industry, Services) model • Calibrates the model using US data • Calculates Austrian sectoral TFP using Austrian sectoral labor allocation • Compares Austrian TFPs to those of transition economies TFP in New EU Members
The Model • Key features for labor reallocation across sectors: • Non-homothetic preferences and agricultural TFP growth drive labor out of agriculture • TFP growth differential and elasticity of substitution between industrial and services output drive labor reallocation in those 2 sectors. • Closed economy TFP in New EU Members
Preferences • Household lives forever, supplies labor to 3 sectors, earns income. • Utility TFP in New EU Members
Technologies • Agriculture uses only labor and land (L=1), and is only used for consumption. With NA the agricultural labor, where TFP in New EU Members
Technologies • Industrial output can be consumed or invested. where • The law of motion of the aggregate capital stock (K) in the economy is given by: where δ is the depreciation rate. TFP in New EU Members
Services • Services are only consumed. where TFP in New EU Members
Solving the Model • A competitive equilibrium is a set of allocations and prices such that:(i) Taking prices as given, the householdmaximizes lifetime utility subject to its budgetconstraint(ii) Taking prices as given, the representativefirm in each sector maximizes profits(iii) Markets clearEquivalent to a social planner’s (SP) problem TFP in New EU Members

Intuition for Solution At a heuristic level, given the calibrated preference parameters: Employment in agriculture determines agricultural TFP. Relative employment between industry and services determines relative TFP between them. Aggregate GDP per capita determines the levels of TFP in industry and services. TFP in New EU Members

Policy Implications • Sectoral differences are important • In some countries catch up is hampered by poor performance in one or more sectors • Structural change not a major drag • Specific policy measures depend on how we believe TFP is determined • Research question: Is sectoral TFP performance linked to nature of reforms such as privatization, governance, regulation, etc. ?
