Chasing the Smokestack: Strategic Policymaking With Multiple Instruments

Empirical evidence suggesting that a considerable amount of horizontal strategic interaction exists amongst governments is important in light of recent devolutionary trends of many important public programs. The empirical approach in these studies typically relies on estimating reaction functions in a uni-dimensional policy framework, where a nonzero slope estimate is interpreted as evidence in support of strategic interactions. While this framework is a useful representation within certain contexts, it is potentially too restrictive; for example, in models of resource competition, localities may use multiple instruments in their recruiting pursuits, leading to potential strategic interactions across policy instruments. In this study, we first develop a simple theoretic construct that includes resource competition in a world of three-dimensional policy choice. The model suggests that while a zero-sloped reaction function may exist for any particular policy, this does not necessarily imply the absence of strategic interactions. We examine the implications of the model empirically using US state-level panel data over the period 1977-1994. The results suggest that important cross-policy strategic interactions exist, lending support in favor of the multi-dimensional framework, and indicate that uni-dimensional frameworks may present lower bound estimates of the degree of strategic interaction.

Corruption and climate change policies: do the bad old days matter?

We study the effect of countries’ historical legacy with corruption on recent climate change policies and on global cooperation. Current policy outcomes build on policy choices made in previous years, and these choices were likely affected by the degree of corruption at the time. Our empirical findings using data for up to 131 countries suggest that accumulated historical experience with corruption is important for today’s policy outcomes, and appears to be more important than the current level of corruption

Trade integration and political turbulence : environmental policy consequences.

This paper contributes to the unresolved issue regarding the effect of economic integration on environmental policymaking. In particular, we discuss the joint impact of trade openness and political stability on environmental policymaking. Our theory predicts that the effect of trade integration on environmental policy is conditional on the degree of political stability. Trade integration affects the stringency of environmental policies due to changes in industry bribery behavior, and the effect is conditional on the degree of political stability. The empirical findings support the theory and are robust to alternative specifications. The stringency enhancing effect on environmental policy of trade integration is greater in politically stable countries

Tobacco Politics and Electoral Accountability in the United States

This paper investigates whether reputation-building strategies guide U.S. governors’ state cigarette tax choices, and whether the federal cigarette tax influences such behavior. Using 1975-2000 data, we find evidence that governors in states with relatively important agricultural tobacco production and tobacco manufacturing, and which are densely populated by smokers, appear prone to reputation-building. Moreover, lame ducks are more prone to raise the state cigarette tax the lower the federal tax

Gubernatorial Reputation and Vertical Tax Externalities: All Smoke, No Fire?

This paper investigates whether reputation-building strategies guide U.S. governors’ responses to changes in federal cigarette taxes (i.e. vertical tax interactions). Using 1975-2000 state cigarette tax data, we find that reputation-building strategies affect the nature of vertical tax externalities. Lame duck governors exhibit a more negative response to changes in the federal cigarette tax. Thus, by reducing the state tax base and by causing a decline in the state tax, an increase in the federal tax rate reduces state tax revenues in states headed by lame ducks

Taxing Under the Influence? : Corruption and U.S. State Beer Taxes

This article examines the effect of state level corruption on state beer taxes in the United States. Our lobby group model predicts that corruption reduces the beer tax, but this effect is conditional on the level of alcohol-related vehicle deaths. Using a panel of state level data from 1982 to 2001, we find that increased corruption is associated with lower state beer tax rates. The magnitude of the effect, however, declines with increases in alcohol-related traffic deaths. Our findings suggest that future empirical work estimating the effect of alcohol taxes on alcohol-related traffic fatalities should treat alcohol taxes as endogenous

Are Politicians Office or Policy Motivated? The Case of U.S. Governors\u27 Environmental Policies

Are elected politicians primarily motivated by holding office, thus choosing environmental policies accordingly? Or are they motivated by the chance to implement their preferred environmental policies? Do governors have character, in the sense that they promise and implement environmental policies consistent with their own preferences? To answer these questions, we study the differences in environmental spending across both re-electable and lame duck governors from the two main political parties. In our empirical analysis, we make use of parametric and non-parametric regression-discontinuity approaches. While re-electable governors do not set significantly different policies, lame duck governors do. We argue that in the area of environmental policy governors appear to be primarily office motivated and lack character

In situ heat treatment in selective laser melted martensitic AISI 420 stainless steels

Published ArticleThe article explores an evolution of a microstructure in AISI 420martensitic stainless steel during selective laser melting. Several upper layers had hardness of 750 HV and contained 21±12 vol.% austenite phase. The final bulk microstructure consisted of thermally decomposed martensitewith hardness of 500–550HV and unusually high, 57±8 vol.%,amount of austenite. Obtained results indicate that duringmanufacturing a partitioning and austenite reversion took place, owing to the thermal cycling of the inner regions duringmanufacturing. Numerical simulation was found plausible to analyze and explain thermally activated processes that occurred in situ. Results of numerical simulation of the thermal cycles in dependence on the processing parameters suggested a possibility to control the thermal processes by variation of the laser energy input

MICROSTRUCTURAL AND THERMAL STABILITY OF SELECTIVE LASER MELTED 316L STAINLESS STEEL SINGLE TRACKS#

Published ArticleTo remove residual stresses, an as-built SLM object is usually post-treated. This treatment can affect the microstructure, changing the final mechanical characteristics. This investigation is focused on the microstructural characterisation of 316L austenitic stainless steel in as-built and annealed conditions. The SLM microstructure was relatively stable up to 900°C, when cell boundaries start to disappear. At higher temperatures, an insignificant grain coarsening was detected. These microstructural changes caused a gradual drop in the hardness. The obtained result is background for the future development of post-treatment regimens to achieve a high level in the final mechanical properties of SLM objects

Pearson cross-correlation in the first four black hole binary mergers

We adopt the Pearson cross-correlation measure to analyze the LIGO Hanford and LIGO Livingston detector data streams around the events GW150914, GW151012,GW151226 and GW170104. We find that the Pearson cross-correlation method is sensitive to these signals, with correlations peaking when the black hole binaries reconstructed by the LIGO Scientific and Virgo Collaborations, are merging. We compare the obtained cross-correlations with the statistical correlation fluctuations arising in simulated Gaussian noise data and in LIGO data at times when no event is claimed. Our results for the significance of the observed cross-correlations are broadly consistent with those announced by the LIGO Scientific and Virgo Collaborations based on matched-filter analysis. In the same data, if we subtract the maximum likelihood waveforms corresponding to the announced signals, no residual cross-correlations persists at a statistically significant level
