As overall price levels rise, firms are willing to produce more. Why?

As overall price levels rise, firms are willing to produce more. Why? Answer: Because the prices of final goods and services tend to increase faster that the prices of inputs → PRICES ARE STICKY. → firms are able to increase revenues faster than costs, and want to produce more.

Why does the aggregate demand curve slope downward?

Why does the aggregate demand curve slope downward? GDP = OUTPUT = NATIONAL EXPENDITURE = C + I + G +NX: 1) CONSUMPTION (C): Changes in price level will change the REAL value of people's wealth and income → increase in overall prices, reduce people's wealth, in terms of real purchasing power. → When people are less wealthy, they consume less creating a NEGATIVE RELATIONSHIP BETWEEN consumption and overall price level → wealth effect. NOTE: if wages increase the same amount as prices does, the purchasing power of those wages stay the same. 2) INVESTMENT (I): when prices rise, the interest rate (price or borrowing) rises too. Higher interest rates leads to less investments. → increase in borrow costs create an INDIRECT negative relationship between the price level and investment spending. 3) GOVERNMENT SPENDING : The government has NO EFFECT on the negative slopping of the demand curve. 4) NET EXPORTS : When the prices in the US increase, goods become relati

What is the aggregate demand curve?

What is the aggregate demand curve? Answer: A curve that shows the relationship between the overall price level in the economy and total demand.

What is the difference between an increase in cost of production and increase in price level?

What is the difference between an increase in cost of production and increase in price level? Answer: An increase in the cost of production shirts the SRAS curve leftward, reducing quantity of output produced at a given price level. An increase in the price level itself → the weighted average of the prices of all goods and services we produce → would cause us to move from one point on the SRAS curve to another point on the same (unmoving) curve.

How do prices, real output, and unemployment behave as the economy responds to a change in aggregate demand?

How do prices, real output, and unemployment behave as the economy responds to a change in aggregate demand? Answer: Beginning from a state of long run equilibrium, an increase in real aggregate demand will, in the short run, because the economy to move up and to the right along its short run aggregate supply curve. As it does so, the prices of final goods will rise, a positive output gap will develop as real output rises above its natural level, and unemployment will fall below its natural rate. After a time, the expected level of input prices will begin to rise as a result of the increases that have taken place in the prices of final goods. As that happens, the economy will move up and to the left along the aggregate demand curve, assuming no further shift in that curve. The price level of final goods will continue to rise, real output will fall back toward its natural level, and unemployment will rise back toward its natural rate. If, after the economy reaches its new equilib

What are the sources of shifts in the aggregate supply curves?

What are the sources of shifts in the aggregate supply curves? Answer: At the intersection of the long and short run aggregate supply curves, the price level of final goods and the expected level of input prices are equal. An increase (or decrease) in the expected level of input prices thus will cause the short run aggregate supply curve to shift up (or down) along the long run aggregate supply curve. The location of the long run aggregate supply curve is determined by the natural level of real output. An increase in natural real output resulting from improved technology or greater availability of productive resources will cause a rightward shift in the long run aggregate supply curve.

What are the conditions that determine the slopes of the short and long run aggregate supply curves?

What are the conditions that determine the slopes of the short and long run aggregate supply curves? Answer: An aggregate supply curve shows the relationship between the quantity of real output supplied (that is, real domestic product) and the average price level of final goods. The slope of the curve depends on what we assume about the way firms expect changes in the prices of final goods to affect input prices. In the long run, it is reasonable to expect input prices to adjust proportionally to changes in the prices of final goods. In that case, firms have no incentive to increase or decrease output, so the long run aggregate supply curve is a vertical line drawn at the economy's natural level of real output. In the short run, actual and expected input prices adjust only gradually to changes in the prices of final goods. Thus, in the short run, firms find it worthwhile to increase both output and prices in response to an increase in demand.

What are some sources of shifts in the aggregate demand curve?

What are some sources of shifts in the aggregate demand curve? Answer: Movements along the aggregate demand curve are associated with changes in the price level of final goods. Changes in other conditions can cause shifts in the curve. Among the sources of shifts are changes in consumer or business expectations, changes in policy regarding government purchases, taxes, and money; and changes in the world economy. Because of the multiplier effect, an initial $1 change in any of the components will cause the curve to shift to the right or left by more than $1.

What are the conditions that determine the slope of the aggregate demand curve?

What are the conditions that determine the slope of the aggregate demand curve? Answer: The aggregate demand curve shows the relationship between real planned expenditure on final goods and the average price level of final goods. The curve has a negative slope because each of the components of real aggregate demand--consumption, planned investment, government purchases, and net exports--varies inversely with the price level.

What are the primary differences between muscular strength and muscular endurance training?

What are the primary differences between muscular strength and muscular endurance training? Muscular strength is a measure of how much force a muscle can exert in a single effort, while muscle endurance describes the ability of muscles to contract repeatedly over time. Muscle strength and endurance develop together: that is, building muscle strength also helps build endurance and vice versa.

How can the training principles be applied to improve muscular strength and muscular endurance?

How can the training principles be applied to improve muscular strength and muscular endurance? To build muscular endurance, an athlete must train her muscles to overcome fatigue. Gains in muscular endurance are not made by increasing the weight lifted, but by increasing the amount of time a muscle spends contracting against resistance. A muscular endurance training program should come after a maximum-strength building phase (high weights, low repetitions), because the greater a muscle's strength, the more force it can exert during muscular endurance training. Muscular endurance training should not be done to muscle failure. If you want to build strength on a particular muscle, you would have to lift weights that work out that particular muscle, such as doing arm curls for biceps, bench presses for triceps/pectoral muscles, etc. If you want to build strength all round, you would have to set up a workout regimen, targeting each muscle group at least once every few days.

What are the training objectives in the load training phase?

What are the training objectives in the load training phase? Answer: To increase muscular endurance, muscular strength, muscle hypertrophy, body composition, movement, function, and health.

How should you address Frequency in the load training phase?

How should you address Frequency in the load training phase? Answer: During the initial months 2-3 weekly workouts appear to be effective, however, as clients become more advanced and train at higher effort levels, more recovery time is needed between successive exercise sessions. If an equal or greater number of reps cannot be completed in training in subsequent workouts, the training frequency should be reduced to 2 days a week.

How should you address Intensity in the load training phase?

How should you address Intensity in the load training phase? Answer: One objective of muscular endurance training is to work the targeted muscle to fatigue in the end range of the anaerobic energy system. For most people, this requires an exercise set that continues for about 75-100 seconds. Given a training speed of 6 seconds per rep, this is a range of 12-16 controlled reps. Generally, 12 reps can be completed with about 70% max resistance and 16 reps can be done with 60% max. Therefore it is recommended that training intensity for muscular endurance be between 60-70% of maximum resistance.

How should you address Reps in the load training phase?

How should you address Reps in the load training phase? Answer: The recommended rep range for enhancing muscular endurance is between 12-16 controlled reps that fatigue the targeted muscles withing 75-100 seconds. The resistance should be increased by about 5% when 16 controlled reps can be completed. This should decrease the rep count by 2-4 reps making them progress back up.

How should you address Sets in the load training phase?

How should you address Sets in the load training phase? Answer: Most programs designed for increasing muscular endurance incorporate multiple sets of each training exercise. Another is to take relatively brief rest periods between successive exercise sets. Muscular strength training emphasizes full recovery between exercise sets while muscular endurance training is typically characterized by rest periods of less than 30 seconds. Therefore it is recommended that clients training for muscular endurance perform 2-3 sets of each with less than 60 seconds between sets.

How should you address Type of Exercise in the load training phase?

How should you address Type of Exercise in the load training phase? Answer: Standard free weight and machine exercises are well suited for muscular endurance because the weightloads can be progressed with consistency and in small increments.

What is the first progression in circuit strength training?

What is the first progression in circuit strength training? Answer: Increase the number of circuits done. Then you can increase resistance by 5%.

How should you address frequency for muscular strength training?

How should you address frequency for muscular strength training? Answer: This causes significant tissue microtrauma that typically requires 72 hours to heal, so clients who complete a total body workout should schedule 2 workouts per week. If they do split routines breaking up the muscle groups they can do 6 days per week with a 3 day period between each muscle group.

How should you address intensity for muscular strength training?

How should you address intensity for muscular strength training? Answer: 70-90% max resistance to begin with. For optimal development, use between 80-90% of the 1RM. Exercises with near-max weightloads that allow 1-3 reps with more than 90% max weight are highly effective. Increase weight over several weeks.

How should you address reps for muscular strength training?

How should you address reps for muscular strength training? Answer: Determined by resistance. This usually involves fewer reps because of the high weightloads. Most people can do 4 reps with 90% weight and 6 with 80%. When 7 reps can be done then increase the load by 5%.

How should you address sets for muscular strength training?

How should you address sets for muscular strength training? Answer: Can be done through single or multiple set training. Maybe start clients with one hard set of each exercise and increase the number of stimulus sets in accordance to client. Clients will need longer recovery periods. This will typically be 2-5 minute periods. Single set programs will take much less time.

How should you address type of exercise for muscular strength training?

How should you address type of exercise for muscular strength training? Answer: Machine and free weights are best. Squats, deadlifts, or leg presses, lunges, step ups, bench press, incline press, shoulder press, and bar dips, seated rows, lat pull downs and pull ups are all best.

How should you address frequency for muscle hypertrophy training?

How should you address frequency for muscle hypertrophy training? Answer: High volume workouts that include several sets of many exercises for each major muscle group. Use split routines. 6 day split is common.

How should you address intensity for muscle hypertrophy training?

How should you address intensity for muscle hypertrophy training? Answer: 70-80% of max. This should increase muscle strength and endurance since it falls between the ranges of both. Moderate weightloads that can be performed a moderate number of reps with little rest between sets.

How should you address reps for muscle hypertrophy training?

How should you address reps for muscle hypertrophy training? Answer: Most can perform 6 reps with 80% max and 12 reps with 70% so 6-12 reps is recommended.

How should you address sets for muscle hypertrophy training?

How should you address sets for muscle hypertrophy training? Answer: They may perform 4 or more exercises for each muscle group and 3-6 sets of each exercise. Bodybuilders usually rest only 30-90 seconds between sets.

How should you address type of exercise for muscle hypertrophy training?

How should you address type of exercise for muscle hypertrophy training? Answer: Combination of free weights and machines to target all muscle groups with emphasis on isolation exercises. Example, they do squats and leg presses to work the quads, hamis, and glutes, then do leg extensions, leg curls, and hip extensions, then adductions and abductions to target each specific muscle.
