This example illustrates that there is no straightforward way to predict forest responses to elevated CO2 from photosynthetic response curves without accounting for no straightforward relationship between the generally observed stimulation of.
Macroeconomics takes an overall view of the economy, which means that it needs to juggle many different concepts including the three macroeconomic goals of growth, low inflation, and low unemployment; the elements of aggregate demand; aggregate supply; and a wide array of economic events and policy decisions.
The vertical line representing potential GDP—the full-employment level of gross domestic product—gradually shifts to the right over time as well. In contrast, the lower aggregate demand curve is much farther from the potential GDP line and hence represents an economy that may be struggling with a recession.
Cyclical unemployment bounces up and down according to the short-run movements of GDP. The long-term, baseline level of unemployment that occurs year in and year out, however, is called the natural rate of unemployment. The natural rate of unemployment is determined by how well the structures of market and government institutions in the economy lead to a matching of workers and employers in the labor market.
Potential GDP can imply different unemployment rates in different economies, depending on the natural rate of unemployment for that economy. On the other hand, rates of inflation generally decline during recessions. One possible trigger is if aggregate demand continues to shift to the right when the economy is already at or near potential GDP and full employment, thus pushing the macroeconomic equilibrium into the steep portion of the aggregate supply curve.
Let's look at diagram A, on the left below. In this diagram, you'll see a shift of aggregate demand to the right.
How the AD/AS model incorporates growth, unemployment, and inflation
In this situation, the aggregate demand in the economy has soared so high that firms in the economy are not capable of producing additional goods because labor and physical capital are fully employed, and so additional increases in aggregate demand can only result in a rise in the price level.
The two graphs show how a shift in aggregate demand or supply can cause inflationary pressure. The aggregate supply curve slopes up because when the price level for outputs increases while the price level of inputs remains fixed, the opportunity for additional profits encourages more production. Potential GDP, or full-employment GDP, is the maximum quantity that an economy can produce given full employment of its existing levels of labor, physical capital, technology, and institutions.
Aggregate demand is the amount of total spending on domestic goods and services in an economy. The downward-sloping aggregate demand curve shows the relationship between the price level for outputs and the quantity of total spending in the economy. Introduction To understand and use a macroeconomic model, we first need to understand how the average price of all goods and services produced in an economy affects the total quantity of output and the total amount of spending on goods and services in that economy.
The aggregate supply curve Firms make decisions about what quantity to supply based on the profits they expect to earn. Profits, in turn, are also determined by the price of the outputs the firm sells and by the price of the inputs—like labor or raw materials—the firm needs to buy. Aggregate supply, or AS, refers to the total quantity of output—in other words, real GDP—firms will produce and sell.
The aggregate supply curve shows the total quantity of output—real GDP—that firms will produce and sell at each price level. The graph below shows an aggregate supply curve.
Let's begin by walking through the elements of the diagram one at a time: The graph shows an upward sloping aggregate supply curve. The slope is gradual between 6, and 9, before become steeper, especially between 9, and 9, The aggregate supply curve.The Phillips Curve (Macro Review) Macro 3.4
The vertical axis shows the price level. Price level is the average price of all goods and services produced in the economy. It's an index number, like the GDP deflator. Wait, what's a GDP deflator again? The GDP deflator is a price index measuring the average prices of all goods and services included in the economy. The reduced amount of photosynthetic proteins per area in shade requires a lower number of chloroplasts.
This in turn requires less space in mesophyll cells Terashima et al. Shade leaves thus have reduced costs per area in terms of nitrogen Pons and Anten and of carbon as the leaf dry mass per area LMA is lower Poorter et al.
A similar shift in the balance between light harvesting and photosynthetic capacity is observed with variation in growth temperature Hikosaka et al. The amount of Rubisco and other components that determine photosynthetic capacity expressed per unit area and per chlorophyll increases at low temperature.
This compensates for the reduced activity of the photosynthetic proteins, whereas light harvesting is largely unaffected by temperature Hikosaka An additional phenomenon associated with acclimation to low growth temperature is increased investment in the capacity of assimilate processing.

The high rate of production of triose-phosphate by the chloroplast cannot be met by the reduced capacity of its utilization in sucrose synthesis as a result of a lower protein activity at low temperature. This leads to sequestering of phosphate in the cytosol, which limits ATP production in the chloroplast.

The limitation of photosynthesis by triose-phosphate utilization TPU is avoided in the cold by increasing the capacity of sucrose synthesis Stitt and Hurry The light saturated photosynthetic rate in the absence of limitation by TPU can be limited by two processes. The limitation by these two processes can be distinguished in CO2 response curves Farquhar et al.
However, this co-limitation Ci at light saturation is temperature dependent, since Jmax increases stronger with temperature than the initial slope of the CO2 response curve, which is determined by VCmax Kirschbaum and Farquhar The relative constancy of the initial slope with temperature is caused by the increasing Michaelis—Menten constant of Rubisco and the increasing oxygenation to carboxylation ratio with increasing temperature.
The adjustment contributes to efficient utilization of resources that are devoted to Jmax and VCmax. The photosynthetic growth irradiance responses as described above has also been documented for Arabidopsis thaliana Walters and cold and warm temperature effects on photosynthetic performance have been extensively investigated as well Stitt and Hurry These studies showed that Arabidopsis is very well capable of acclimation to shade and cold. The latter is not surprising since most of its populations exhibit a winter annual life history Mitchell-Olds and Schmittwhich means that much of its growth occurs in the cool season.
However, the possible interacting effects of growth temperature and irradiance on photosynthetic characteristics have not been investigated in this or in other species. The first question to be addressed is to what extent the effect on photosynthetic acclimation of growth temperature depends on growth irradiance and vice versa. It is hypothesized that the two factors may interact, since several aspects of photosynthetic acclimation are shared.
To investigate the interaction, Arabidopsis was grown at two levels of irradiance and temperature in a factorial design. Since the plants were grown in constant conditions, developmental acclimation is addressed here as distinguished from dynamic acclimation in response to a change in growth conditions that is regulated differently Athanasiou et al. Arabidopsis thaliana has a large geographical distribution Koornneef et al.
