Patience and the Wealth of Nations Paper by: Thomas Dohmen, Benjamin Enke, Armin Falk, David Huffman and Uwe Sunde 01/2015 Topics in Behavioral and Experimental Economics SS 2015 Presentation: Dominik Schaufler Conceptual Framework Source: Figure 1, Patience and the Wealth of Nation, p. 4 Hypotheses • H1: At the aggregate level, patience exhibits a positive reduced-form correlation with income levels and income growth • H2: Patience is correlated with proximate determinants, in terms of both their levels and corresponding accumulation processes. In addition, none of the proximate determinants alone fully captures the explanatory content of patience with respect to national income. Hypotheses • H3: The positive reduced-form relationship between patience and income, and the association between patience and accumulation decisions, extends to disaggregate data at the regional and individual level. Data collection • Global Preference Survey, 2012, 76 countries • 4 noteworthy features: – Preference measures obtained in a comparable way – Representative population samples – Reflects geographical representativeness – Experimental validated survey items Measure of patience • Quantitative: Staircase measure – choice between hypothetical payment today or payment in 1 year – expressed in local currency • Qualitative: self assessment on 11 point Scale how willing are you to give something up (completely unwilling to do so – very willing to do so) • Linear combination makes up patience measure • Patience = 0.711 Staircase measure + 0,288 Qualitative measure World map of patience Source: Figure 2, Patience and the Wealth of Nation Source: Table 1, Patience and the Wealth of Nation Sub Samples and Additional measures • Patience and Effect on Continents odes the relationship exist within continents? – Patience explains around 40% of the variation within continents (Continents, OECD, Colonized) • Alternative measures – GDP/worker, HDI, subjective statements of well being • relationship not restricted to GDP/capita as measure. Measuring Preferences Unobserved factors? • 3 potential problematic areas: – Financial environment in terms of inflation, interest rate, borrowing constraints – Context or culture specific interpretations – Systematic shortcuts due to cognitive limitations Historical Income and growth rates • If deep cultural roots there should be persistence over time – historical prediction should be possible – Account for population flows • Higher steady state but also faster growth? – 1820, 1870, 1925, 1950, 1975, 2010 • Unconditional correlation • Control for log per capita and continent fixed effects Role of proximate determinants • Can any single proximate determinant fully account for the relationship between patience and national income? – Patience and physical Capital (about a third of the variation explained) – Patience and Human Capital (about 40% of variation explained) Patience, factor productivity and institutions Total factor productivity, R&D expenditures as % of GDP, # Researchers in R&D, Global innovation index Not only accumulation of factors but also relevant for accumulation of knowledge + productivity Institutions: democratic quality, property rights, social infrastructure index, S&P long term credit rating Patience is a strong correlate of democracy, property rights and social infrastructure Condition on proximate determinants • Relationship should weaken if conditioned on proximate determinants • it does, but patience remains significant • No proximate determinate alone fully accounts for explanatory content of patience Patience within Countries • (3rd Hypotheses) – Regional level (55 countries, 712 regions) • H3 confirmed, regions are influenced by different levels of patience – Individual level • Within countries more patient people tend to be richer and have a higher education. • Relationship holds at the individual level Conclusion • No identification of causal effects • Existence of third factors? • Reverse causality? • Framework with time preference as relevant driver empirically validated.
