Labor Productivity of Apple Harvest Workers

Capital, Labor, and Productivity

IN A PREVIOUS PAPER I explored two suggestions about how to understand time-series and cross-country variations in measured total factor productivity growth: increases in the labor force might slow technological change and increases in capital might speed it up. 1 Neither suggestion was new. The conjecture about the effect of labor dates back, at least, to attempts to explain the divergence in ...

Nondestructive Determination of ‘golden Delicious’ Apple Quality and Harvest Maturity

The usefulness of nondestructive methods for measuring chlorophyll content in skin of ‘Golden Delicious’ apples and for evaluating quality parameters and fruit maturity using optical reflectance spectrometry was studied. The fruit weight, firmness, total soluble solids content and titratable acidity during vegetation period and short-term storage at 10°C of ‘Golden Delicious’ apples were measur...

The Physiology of Apple Pre-harvest Fruit Drop

As apples ripen they begin to produce large amounts of the ripening hormone, ethylene. Ethylene stimulates fruit softening and the formation of an abscission zone in the stem. Ethylene stimulates the production of enzymes (cellulase and polyglacturonase) that break down the cell walls and the glue that holds cell walls together in the abscission zone of the stem, leaving the fruit connected to ...

Immigration, Labor Markets, and Productivity

According to a survey in 2008, about 50 percent of Americans perceived immigration as a problem rather than as an opportunity (Transatlantic Trends 2008). Similar surveys conducted in the prerecession years of 2007 and before also showed that Americans were much less supportive of more open immigration policies than they were of other aspects of globalization such as free trade or free capital ...
