Minimum Wages and Poverty
The principal justification for minimum wage legislation resides in improving the economic condition of low-wage workers. Most previous analyses of the distributional effects of minimum wages have been confined to simulation exercises employing rather restrictive assumptions that guarantee the conclusion that an increase in the minimum wage reduces poverty. In contrast, we adopt a more flexible "reduced-form" approach that links increases in both federal and state minima to contemporaneous changes in poverty rates. For the period 1983-96, we find indication of a poverty-reducing effect of minimum wages among older junior-high dropouts and among teenagers. --
Minimum Wage Increases Under Straightened Circumstances
Do apparently large minimum wage increases in an environment of recession produce clearer evidence of disemployment effects than is typically observed in the new minimum wage literature? This paper augments the sparse literature on the most recent increases in the U.S. minimum wage, using three different data sets and the two main estimation strategies for handling geographically-disparate trends. The evidence is generally unsupportive of negative employment effects, still less of a 'recessionary multiplier.' Minimum wage workers seem to be concentrated in sectors of the economy for which the labor demand response to wage mandates is minimal.minimum wages, disemployment, earnings, low-wage sectors, geographically-disparate employment trends, recession
The Effect of Minimum Wages on Labor Market Outcomes: County-Level Estimates from the Restaurant-and-Bar Sector
We use county-level data on employment and earnings in the restaurant-and-bar sector to evaluate the impact of minimum wage changes on low-wage labor markets. Our empirical approach is similar to the literature that has used state-level panel data to estimate minimum-wage impacts, with the difference that we focus on a particular sector rather than demographic group. Our estimated models are consistent with a simple competitive model of the restaurant-and-bar labor market in which supply-and-demand factors affect both the equilibrium outcome and the probability that a minimum wage will be binding in any given time period. Our evidence does not suggest that minimum wages reduce employment in the overall restaurant-and-bar sector, after controls for trends in sector employment at the county level are incorporated in the model. Employment in this sector appears to exhibit a downward long-term trend in states that have increased their minimum wages relative to states that have not, thereby predisposing fixed-effects estimates towards finding negative employment effects.

New Estimates of the Effects of Minimum Wages in the U.S. Retail Trade Sector
This paper examines the impact of minimum wages on earnings and employment in selected branches of the retail-trade sector, 1990-2005, using county-level data on employment and a panel regression framework that allows for county-specific trends in sectoral outcomes. We focus on particular subsectors within retail trade that are identified as particularly low-wage. We find little evidence of disemployment effects once we allow for geographic-specific trends. Rather, in many sectors the evidence suggests modest (but robust) positive employment effects. One explanation we consider for these ‘perverse’ effects is that minimum wages may have significant influences on product demand shifts.border county analysis, spatial trends, county-level data, wages and employment, minimum wages, unions, right-to-work states
Minimum Wage Increases in a Soft U.S. Economy
Do apparently large minimum wage increases in an environment of straightened economic circumstances produce clearer evidence of disemployment effects than is typically reported in the new economics of the minimum wage? The present paper augments the sparse literature covering the very latest increases in the U.S. minimum wage, using three different data sets and the principal estimation strategies for handling geographically-disparate trends. Despite the seemingly more favorable milieu for identifying displacement effects, and although our treatment calls into question one well-received estimation strategy, our preferred specification generally fails to support a finding of negative employment effects. That is to say, minimum-wage workers are apparently concentrated in sectors of the economy for which the labor demand response to statutory wage hikes is minimal. Popular concern with a “recessionary multiplier” thus seems overdone.Minimum wages, Disemployment, Earnings, Low-wage sectors, Geographically-disparate employment trends, Recession
Problems posing as solutions: Criticising pragmatism as a paradigm for mixed research
Mixed research is a methodology of growing importance both within and without education. This type of research forces researchers to reconcile conflicting ways of justifying and understanding research with results that have the potential to be forward pointing for all researchers. As mixed research has grown, mixed research has gained an increasingly solidified identity which is increasingly associated with the pragmatic paradigm. This paper seeks to describe and criticise pragmatism as a paradigm for mixed research. We identify six features of pragmatism which we argue render it unfit for purpose. 1. That it is a “paradigm of convenience” 2. That it takes a consequentialist view of good research. 3. That it takes a consequentialist view of truth. 4. That it assumes the answers to epistemic questions is “somewhere in the middle” 5. That it priorities the research question, rather than ontology or epistemology 6. That it treats itself as a prerequisite for mixed research. We argue that in prioritising flexibility and practicality over principles, pragmatism loses the ability to offer guidance to researchers. Furthermore, many of the issues with pragmatism arise from a conflation of paradigm and method. I.e., by thinking that there are quantitative and qualitative paradigms. We conclude that traditional paradigms are better served to act as a paradigm for mixed research

Development of low cost packaged fibre optic sensors for use in reinforced concrete structures
There is an ongoing need to measure strains in reinforced concrete structures more reliably and under a range of circumstances e.g. long term durability (such as effects of cracking and reinforcement corrosion), response to normal working loads and response under abnormal load conditions. Fibre optic sensors have considerable potential for this purpose and have the additional advantages, including of immunity to electromagnetic interference and light weight (Grattan et al., 2000). This is important in railway scenarios and particularly so when the lines are electrified. Their small size allows for easy installation. However, their use as commercial ‘packaged’ devices (traditionally seen as necessary to achieve adequate robustness) is limited by their high cost relative to other sensor devices such as encapsulated electric resistance strain gauges. This paper describes preliminary work to produce a cost-effective and easy-to-use technique for encapsulating fibre optic sensors in resin using 3D printing techniques to produce a robust, inexpensive ‘packaged’ sensor system suitable for use with concrete structures. The work done to date has shown this to be a convenient and economical way of producing multiple sensors which were suitable for both surface mounting and embedment in reinforced concrete structures. The proof-of-concept testing to which the trial packages were subjected is described in the paper and the results indicate that 3D printed packages have considerable potential for further development and use in a variety of civil engineering applications, competing well with more conventional sensor systems
