Commentary on Politics of Urbanism: Seeing Like a City by Warren Magnusson

Politics of Urbanism: Seeing Like a City is Warren Magnusson's most recent book. It will find a permanent place as a key contribution in the annals of urban studies, urban politics, political and state theory and international relations, marking a turning point in the way scholars, activists and policymakers see the world. In particular, Magnusson fundamentally questions how we understand and analyse our world from the perspective of the state (the illusion of the sovereign), suggesting we shift instead to the perspective of the city (with its multiplicity of authorities). ‘How welcome should this be?’ is the question that I put to three Canadian colleagues — Roger Keil, Andrew Sancton and Zack Taylor — at the 2011 meeting of the Canadian Political Science Association in Waterloo, ON, Canada. Their answers follow a summary of this rather concise and very readable book that Serena Kataoka and I prepared to introduce those commentaries.     

Increasing Public Expenditure: Wagner's Law in OECD Countries

Abstract. The paper proposes a panel cointegration analysis of the joint development of government expenditure and economic growth in 23 Organization Economic Cooperation and Development countries. The empirical evidence provides indication of a structural positive correlation between public spending and per‐capita gross domestic product (GDP), which is consistent with the so‐called Wagner's law. A long‐run elasticity larger than 1 suggests a more than proportional increase of government expenditure with respect to economic activity. In addition, according to the spirit of the law, we found that the correlation is usually higher in countries with lower per‐capita GDP, suggesting that the catching‐up period is characterized by a stronger development of government activities with respect to economies in a more advanced state of development.     

Consumption Responses to a Large Shock to Financial Wealth: Evidence from Italy

We estimate marginal propensities to consume from wealth shocks. We exploit large asset-price shocks in 2007–2008 and household-level panel data to implement instrumental variables. A fall of one euro in risky financial wealth resulted in cuts to annual total (non-durable) consumption of 8.5–9 (5.5–5.7) cents, with small effects on food spending. Effects seem stronger for lower-wealth or indebted households, but significant responses from wealthier households and those without mortgages are important for our baseline results. Counterfactuals indicate financial-wealth effects were relatively important for consumption falls in Italy in 2007–2008. The estimated effects are consistent with a simulated life-cycle model capturing the wealth shock.     

Measurement and Allocation of Capital Inputs With Taxes: A Sensitivity Analysis for OECD Countries

Taxes affect the measurement of capital inputs. The paper provides an assessment of these impacts in a cross‐country framework where heterogeneity of corporate taxation across industries and asset types is accounted for. The results show that taxes change the relative prices of capital types, which, in turn, has implications on the estimated capital quality and reallocation effects in the traditional growth accounting framework. Omitting tax parameters is a source of mismeasurement, particularly when the rental price of capital assets is constructed using an external rate of return, leading to biased capital costs and profits rates. It is shown that differential taxation results in a deadweight loss in terms of misallocated capital inputs, predominantly due to composition effects within industries.
